Java<\/a><\/strong> yra populiari kalba, u\u017eimanti tvirt\u0105 viet\u0105 pasaulyje programin\u0117s \u012frangos k\u016brimas<\/a><\/strong>. Tai stipri ir universali programavimo kalba. Ma\u017edaug 3 mlrd. prietais\u0173 visame pasaulyje veikia su Java<\/strong> tod\u0117l j\u012f naudojant buvo padaryta ma\u017eiausiai 3 mlrd. klaid\u0173. \u0160iame straipsnyje daugiausia d\u0117mesio skirsime tam, kaip daugiau j\u0173 nedaryti.<\/p>\n\n\n\n

1. Vienalaikio keitimo i\u0161imties gavimas<\/h2>\n\n\n\n

Tai bene da\u017eniausiai pasitaikanti klaida, su kuria susid\u016briau. Savo karjeros prad\u017eioje ir a\u0161 j\u0105 dariau daugyb\u0119 kart\u0173. \u0160i klaida \u012fvyksta, kai bandote keisti kolekcij\u0105, kol j\u0105 iteruojate. \u012era\u0161as ConcurrentModificationException<\/code> taip pat gali b\u016bti i\u0161kelta, kai dirbate su keliais srautais, ta\u010diau dabar sutelkime d\u0117mes\u012f \u012f pagrindin\u012f scenarij\u0173.<\/p>\n\n\n\n

Tarkime, kad turite Kolekcija<\/code> naudotoj\u0173, kai kurie i\u0161 j\u0173 yra suaugusieji, o kai kurie - ne. J\u016bs\u0173 u\u017eduotis - i\u0161filtruoti vaikus.<\/p>\n\n\n\n

for (Vartotojas : vartotojai) {\n\n   if (!user.isAdult()) {\n\n       users.remove(user);\n\n   }\n\n}\n<\/code><\/pre>\n\n\n\n
Vykdant min\u0117t\u0105 kodas<\/a> baigiasi gavus ConcurrentModificationException<\/code>. Kur suklydome? Prie\u0161 baigdami iteracij\u0105 paband\u0117me pa\u0161alinti kai kuriuos elementus. D\u0117l to ir atsirado i\u0161imtis.<\/p>\n\n\n\n
Kaip to i\u0161vengti?<\/h3>\n\n\n\n
Tokiu atveju gali pad\u0117ti keli b\u016bdai. Vis\u0173 pirma, pasinaudokite Java<\/strong> 8 gerumas - Srautas<\/code>.<\/p>\n\n\n\n
List adults = users.stream()\n\n       .filter(User::isAdult)\n\n       .toList();\n<\/code><\/pre>\n\n\n\n
Naudojant Predikatas<\/code> filtras, atlikome atvirk\u0161tin\u0119 ankstesnei s\u0105lygai funkcij\u0105 - dabar nustatome elementus, kuriuos reikia \u012ftraukti. Tokio metodo privalumas yra tas, kad po pa\u0161alinimo lengva grandininiu b\u016bdu sujungti kitas funkcijas, pvz. \u017eem\u0117lapis<\/code>. Bet d\u0117l Dievo meil\u0117s. nebandykite daryti ka\u017eko pana\u0161aus \u012f tai, kas apra\u0161yta toliau:<\/p>\n\n\n\n
users.stream()\n\n       .filter(v -> !v.isAdult())\n\n       .forEach(users::remove);\n<\/code><\/pre>\n\n\n\n
Jis taip pat gali atsidurti ConcurrentModificationException<\/code> nes kei\u010diate srauto \u0161altin\u012f. Be to, gali atsirasti daugiau i\u0161im\u010di\u0173, kurias bus nelengva pa\u0161alinti.<\/p>\n\n\n\n
I\u0161spr\u0119sti ConcurrentModificationException<\/code> taip pat galite pereiti prie tiesioginio Iteratorius<\/code> ir jo pa\u0161alinti()<\/code> metod\u0105, arba galite tiesiog nepa\u0161alinti element\u0173 iteracijos metu. Ta\u010diau a\u0161 rekomenduoju naudoti Srautai<\/code> - 2022 m.<\/p>\n\n\n\n
2. Slapta\u017eod\u017ei\u0173 saugojimas kaip eilut\u0117s<\/h2>\n\n\n\n
Kadangi vis labiau \u012fsitraukiu \u012f kibernetin\u0119 saug\u0105, neb\u016b\u010diau teisingas sau, jei nepamin\u0117\u010diau bent vieno \"Java\" klaida<\/strong> d\u0117l to gali kilti saugumo problem\u0173. I\u0161 naudotoj\u0173 gaut\u0173 slapta\u017eod\u017ei\u0173 saugojimas Stygos<\/code> objektas yra b\u016btent tai, ko tur\u0117tum\u0117te bijoti.<\/p>\n\n\n\n
Problema (o gal privalumas) Stygos<\/code> yra tai, kad jis yra nekintamas. Kibernetiniame pasaulyje tai kelia potenciali\u0105 gr\u0117sm\u0119, nes negalima i\u0161trinti kart\u0105 sukurtos vert\u0117s. Stygos<\/code> objektas. U\u017epuolikas, gav\u0119s prieig\u0105 prie j\u016bs\u0173 kompiuterio atminties, joje gali rasti paprasto teksto slapta\u017eod\u017eius.<\/p>\n\n\n\n
Antra, eilut\u0117s Java<\/strong> yra internuojami JVM ir saugomi PermGen erdv\u0117je arba kr\u016bvos erdv\u0117je. Kai sukuriate Stygos<\/code> objekt\u0105, jis \u012fra\u0161omas \u012f talpykl\u0105 ir pa\u0161alinamas tik tada, kai \u0161iuk\u0161li\u0173 surink\u0117jas pradeda atlikti savo darb\u0105. Negalite b\u016bti tikri, kada j\u016bs\u0173 slapta\u017eodis bus pa\u0161alintas i\u0161 \"String\" fondo, nes \u0161iuk\u0161li\u0173 surink\u0117jas veikia nedeterministi\u0161kai.<\/p>\n\n\n\n
Kaip to i\u0161vengti?<\/h3>\n\n\n\n
Rekomenduojama naudoti char[]<\/code> arba, dar geriau, bibliotek\u0105, kuri palaiko slapta\u017eod\u017ei\u0173 saugojim\u0105 kaip char[]<\/code>, pvz.Password4j<\/a>. . char[]<\/code> masyv\u0105 galima keisti, tod\u0117l po inicializavimo j\u012f galima modifikuoti. Apdoroj\u0119 slapta\u017eod\u012f, galite tiesiog i\u0161trinti char[]<\/code> slapta\u017eod\u017ei\u0173 masyv\u0105 \u012fra\u0161ydami \u012f j\u012f atsitiktinius simbolius. Jei \u012fsilau\u017e\u0117liai gaus prieig\u0105 prie kompiuterio atminties, jie pamatys tik kelias atsitiktines reik\u0161mes, kurios neturi nieko bendra su naudotoj\u0173 slapta\u017eod\u017eiais.<\/p>\n\n\n\n
3. I\u0161im\u010di\u0173 (ne)tvarkymas<\/h2>\n\n\n\n
Naujokai ir labiau pa\u017eeng\u0119 programuotojai ne\u017eino, kaip teisingai tvarkyti i\u0161imtis. Pagrindin\u0117 j\u0173 nuod\u0117m\u0117 \u0161iuo klausimu - tiesiog jas ignoruoti. TAI NIEKADA N\u0116RA GERAS PO\u017dI\u016aRIS.<\/p>\n\n\n\n
Deja, negalime pateikti sprendimo, kuris tikt\u0173 kiekvienam I\u0161imtis<\/code>s\" scenarijus, su kuriuo susiduriate. Apie kiekvien\u0105 atvej\u012f turite galvoti atskirai. Ta\u010diau galime patarti, kaip prad\u0117ti nagrin\u0117ti \u0161i\u0105 tem\u0105.<\/p>\n\n\n\n
Kaip to i\u0161vengti?<\/h3>\n\n\n\n
    \n
  1. \n
    Ignoruoti I\u0161imtis<\/code>s niekada n\u0117ra gera praktika. I\u0161imtis<\/code>\u012fterpiamos d\u0117l tam tikr\u0173 prie\u017eas\u010di\u0173, tod\u0117l nereik\u0117t\u0173 j\u0173 ignoruoti.<\/p>\n<\/li>\n\n\n\n
  2. \n
    try {...} catch(I\u0161imtis e) { log(e); }<\/code> retai kada yra teisingas po\u017ei\u016bris \u012f I\u0161imtis<\/code> tvarkymas.<\/p>\n<\/li>\n\n\n\n
  3. \n
    Rethrow I\u0161imtis<\/code>, rodyti naudotojui klaidos dialogo lang\u0105 arba bent jau \u012ftraukti i\u0161sam\u0173 prane\u0161im\u0105 \u012f \u017eurnal\u0105.<\/p>\n<\/li>\n\n\n\n
  4. \n
    Jei palikote neapdorotas i\u0161imtis (o taip netur\u0117t\u0173 b\u016bti), bent jau paai\u0161kinkite tai komentare.<\/p>\n<\/li>\n<\/ol>\n\n\n\n
    4. Nulin\u0117s vert\u0117s naudojimas<\/h2>\n\n\n\n
    Deja, gana da\u017enai pasitaiko \"Java\" funkcij\u0173, kurios kai kuriais atvejais gr\u0105\u017eina null<\/code>. Problema yra ta, kad tokia funkcija priver\u010dia klient\u0105 atlikti rezultato nulin\u012f patikrinim\u0105. Jei to neb\u016bt\u0173 padaryta, NullPointerException<\/code> i\u0161metamas.<\/p>\n\n\n\n
    Kitas dalykas yra perduoti null<\/code> vert\u0117. Kod\u0117l apie tai net pagalvojote? Tokiu atveju funkcija turi atlikti nulin\u0117s reik\u0161m\u0117s patikrinim\u0105. Kai naudojate tre\u010di\u0173j\u0173 \u0161ali\u0173 bibliotekas, negalite keisti funkcij\u0173 vidaus. K\u0105 tada daryti?<\/p>\n\n\n\n
    Dar svarbiau, kad kiti k\u016br\u0117jai, kurie skaito j\u016bs\u0173 kod\u0105 ir mato, kad perduodate null<\/code> tikriausiai nesuprasite, kod\u0117l pasirinkote tok\u012f keist\u0105 b\u016bd\u0105 savo funkcijai \u012fgyvendinti.<\/p>\n\n\n\n
    Kaip to i\u0161vengti?<\/h3>\n\n\n\n
    Negr\u0105\u017einkite null<\/code> vert\u0117! Niekada! Jei j\u016bs\u0173 funkcija gr\u0105\u017eina tam tikro tipo Kolekcija<\/code>, galite tiesiog gr\u0105\u017einti tu\u0161\u010di\u0105 Kolekcija<\/code>. Jei dirbate su pavieniais objektais, galite naudoti nulinio objekto projektavimo \u0161ablon\u0105. Kadangi Java<\/strong> 8, jis \u012fgyvendinamas kaip Pasirinktinai<\/code>. Be to, ma\u017eiausiai rekomenduojamas b\u016bdas yra kelti I\u0161imtis<\/code>.<\/p>\n\n\n\n
    5. Sunkus eilut\u0117s sujungimas<\/h2>\n\n\n\n
    Tik\u0117kim\u0117s, kad tai n\u0117ra j\u016bs\u0173 klaida, nes tai populiariausias (o gal antras pagal populiarum\u0105 po \"FizzBuzz\") interviu klausimas. Kaip jau tur\u0117tum\u0117te \u017einoti, a Stygos<\/code> objektas yra nekei\u010diamas Java<\/strong> - Kart\u0105 sukurtos, jos negalima keisti. Taigi konkatenavimas Stygos<\/code> raid\u0117s rei\u0161kia daug nereikalingo atminties priskyrimo. sujungimas Stygos<\/code> objektus kiekvien\u0105 kart\u0105 reikia sukurti laikin\u0105 StringBuilder<\/code> objekt\u0105 ir pakei\u010diant j\u012f atgal \u012f eilut\u0119. Tod\u0117l \u0161is sprendimas visi\u0161kai netinka, jei norime sujungti daug simboli\u0173.<\/p>\n\n\n\n
    Kaip to i\u0161vengti?<\/h3>\n\n\n\n
    Nor\u0117dami i\u0161spr\u0119sti \u0161i\u0105 problem\u0105, naudokite StringBuilder<\/code>. Taip sukuriamas kei\u010diamas objektas, kuriuo galima lengvai manipuliuoti. \u017dinoma, visada galite naudoti StringBuffer<\/code> jei j\u016bs\u0173 projektas<\/a> naudojamas lygiagre\u010diai.<\/p>\n\n\n\n
    6. Esam\u0173 sprendim\u0173 nenaudojimas<\/h2>\n\n\n\n
    Kuriant programin\u0119 \u012frang\u0105 b\u016btina i\u0161manyti kalbos, kuria ra\u0161ote, pagrindus, ta\u010diau to nepakanka. Daugel\u012f algoritmini\u0173 problem\u0173, su kuriomis susid\u016br\u0117te \u012fgyvendindami nauj\u0105 funkcij\u0105, jau i\u0161sprend\u0117 kas nors kitas. Pernelyg daug kart\u0173 ma\u010diau, kaip kas nors \u012fgyvendina saugumo algoritm\u0105 nuo nulio. Toks po\u017ei\u016bris yra link\u0119s \u012f klaidas. Vienas \u017emogus negali nuodugniai i\u0161bandyti tokio sud\u0117tingo sprendimo. Kolektyvin\u0117s \u017einios komanda<\/a> kuri\u0105 sudaro vidutini\u0161kai pa\u017eeng\u0119 programuotojai, beveik visada yra geresn\u0117 u\u017e vieno stebuklingo programuotojo didyb\u0119. \"Java\" programuotojas<\/a><\/strong>. Nereikia i\u0161radin\u0117ti dvira\u010dio - tereikia pritaikyti esam\u0105 sprendim\u0105 pagal savo poreikius.<\/p>\n\n\n\n
    Kaip to i\u0161vengti?<\/h3>\n\n\n\n
    Pabandykite ie\u0161koti bibliotek\u0173, kuriose sprend\u017eiama problema, su kuria dirbate. Pabandykite rasti pana\u0161i\u0173 sprendim\u0173. Daugelis bibliotek\u0173, kurias galima rasti \u017einiatinklio svetain\u0117<\/a> yra nemokamos, jas patobulino ir i\u0161band\u0117 patyr\u0119 k\u016br\u0117jai ir visa \"Java\" bendruomen\u0117. Nebijokite jomis pasinaudoti.<\/p>\n\n\n\n
    7. Nerandama pakankamai laiko testams ra\u0161yti<\/h2>\n\n\n\n
    Labai norisi tik\u0117ti, kad m\u016bs\u0173 kodas visada veiks tobulai. Kodo test\u0173 nera\u0161ymas yra did\u017eiausia nuod\u0117m\u0117 Java programin\u0117s \u012frangos k\u016br\u0117jai<\/a><\/strong>. Daugelis i\u0161 mus<\/a> teikia pirmenyb\u0119 rankiniams ir tiriamiesiems testams, o ne vienet\u0173 testams, o tai yra beproti\u0161ka.  Kam gai\u0161ti laik\u0105 ra\u0161ant testus, jei gali susitelkti \u012f geriausio pasaulyje kodo, kuris tikrai neturi klaid\u0173, pateikim\u0105 savo projektui?&ltjoke>. Pasirodo, realyb\u0117 yra \u017eiauri ir mes negalime pateikti auk\u0161tos kokyb\u0117s kodo nera\u0161ydami test\u0173.<\/p>\n\n\n\n
    Kaip to i\u0161vengti?<\/h3>\n\n\n\n
    Visada tur\u0117tum\u0117te parengti savo kodo testus. \u017dinau, kad TDD metod\u0105 n\u0117ra taip lengva pri\u017ei\u016br\u0117ti, ta\u010diau bent jau tur\u0117tum\u0117te pateikti testus, kurie apimt\u0173 visas s\u0105lygas, kuriomis j\u016bs\u0173 kodas gali b\u016bti paleistas. Tai apima ir i\u0161skirtini\u0173 situacij\u0173 testavim\u0105. Vieneto testai yra b\u016btini. Juos turite pateikti kiekvienai savo projekto funkcijai, jei norite u\u017etikrinti, kad j\u016bs\u0173 kod\u0105 b\u016bt\u0173 lengva refaktorizuoti ir pl\u0117sti toliau j\u012f vystant. <\/p>\n\n\n\n
    Dar vienas dalykas. Palaikykite auk\u0161t\u0105 savo bandomojo kodo standart\u0105 - bus verta. Tai d\u0117d\u0117s Bobo patarimas, ir a\u0161 jam visi\u0161kai pritariu.<\/p>\n\n\n\n
    Be to, nepamir\u0161kite ir kit\u0173 tip\u0173 test\u0173. Integracijos testai - tai dalykas, \u012f kur\u012f tur\u0117tum\u0117te atsi\u017evelgti kiekviename projekte.<\/p>\n\n\n\n
    8. Pamir\u0161ti prieigos modifikatorius<\/h2>\n\n\n\n
    Privatus ir vie\u0161as, tiesa? Kaip galime juos pamir\u0161ti. Pasirodo, j\u0173 yra ir daugiau. Kai pirm\u0105 kart\u0105 prad\u0117jote mokytis Java<\/strong>, tikrai su\u017einojote apie saugomus prieigos modifikatorius. Kai kuriais atvejais jie gali b\u016bti naudingi, tod\u0117l verta \u017einoti apie j\u0173 egzistavim\u0105.<\/p>\n\n\n\n
    \"Java\" k\u016br\u0117jai<\/a><\/strong> da\u017enai pamir\u0161tama apie paketo apimt\u012f. Lengva nepamir\u0161ti apie jos naudojim\u0105, nes ji yra numanoma ir nereikalauja joki\u0173 Java<\/strong> rakta\u017eod\u017eiai. Paketo apimtis yra svarbi. Ji leid\u017eia testuoti apsaugot\u0105 metod\u0105. Apsaugoti elementai pasiekiami i\u0161 testuojamos klas\u0117s kelio, jei paketas yra tas pats.<\/p>\n\n\n\n
    Kaip to i\u0161vengti?<\/h3>\n\n\n\n
    Nepamir\u0161kite apie saugom\u0105 modifikatori\u0173 ir tai, kad paketo apimtis leid\u017eia j\u012f i\u0161bandyti.<\/p>\n\n\n\n
    9. Grynosios JavaEE, o ne \"Spring\" naudojimas<\/h2>\n\n\n\n
    Kitas \u017eingsnis po mokymosi Java<\/strong> SE yra i\u0161mokti paleisti Java<\/strong> serveriuose, kaip sukurti \u012fmon\u0117s lygmens program\u0105.<\/p>\n\n\n\n
    Naujokai da\u017enai patenka \u012f sp\u0105stus mokydamiesi JavaEE, nes apie j\u0105 yra daugyb\u0117 vadov\u0117li\u0173. Netgi \"M\u0105stymas Java \"Java\" programuotojai<\/strong>' biblijoje minima JavaEE ir nieko nekalbama apie kitas parinktis.<\/p>\n\n\n\n
    Kaip to i\u0161vengti?<\/h3>\n\n\n\n
    \"JavaEE\" yra praeities daina. \u0160iandien \"Spring\" yra pagrindinis dalykas, o \"Java EE\" yra tiesiog gra\u017eus dalykas. Kiekviena \u0161iuolaikin\u0117 \u012fmon\u0117s lygio programa naudoja \"Spring\", tod\u0117l tur\u0117tum\u0117te tvirtai apsvarstyti galimyb\u0119 i\u0161mokti \u010dia<\/a>.<\/p>\n\n\n\n
