Muutumatud objektid on kasulikud olukordades, kus objekti olekut ei tohiks muuta, n\u00e4iteks mitmesuunalistes keskkondades, kus samaaegne juurdep\u00e4\u00e4s muutuvatele objektidele v\u00f5ib p\u00f5hjustada v\u00f5idujooksu tingimusi ja <a href=\"https:\/\/thecodest.co\/et\/blog\/app-data-collection-security-risks-value-and-types-explored\/\">andmed<\/a> korruptsioon.<\/p>\n<p>Muutumatutel objektidel on mitmeid eeliseid muutuvate objektide ees. Esiteks on need niidikindlad ja neid saab turvaliselt jagada niitide vahel ilma s\u00fcnkroniseerimise vajaduseta. Teiseks on neid lihtsam p\u00f5hjendada, kuna nende olek ei saa ootamatult muutuda. Kolmandaks saab neid kasutada v\u00f5tmetena objektides <a href=\"https:\/\/thecodest.co\/et\/blog\/hash-to-use-or-not-to-use\/\">hash<\/a> tabelid ja komplektid, kuna nende hash-v\u00e4\u00e4rtus on fikseeritud ja ei muutu aja jooksul.<\/p>\n<p>N\u00e4iteid muutumatute objektide kohta <a href=\"https:\/\/thecodest.co\/et\/blog\/find-the-right-java-developer-now\/\">Java<\/a> h\u00f5lmavad String, Integer ja LocalDate. Kui String-objekt on loodud, ei saa selle v\u00e4\u00e4rtust enam muuta. Iga katse seda muuta toob kaasa uue String-objekti loomise uuendatud v\u00e4\u00e4rtusega.

M\u00f5nel juhul on muutuvad objektid sobivamad, n\u00e4iteks kui objekti olekut tuleb sageli uuendada. Sellistel juhtudel on oluline tagada, et juurdep\u00e4\u00e4s muutuvatele objektidele oleks s\u00fcnkroniseeritud, et v\u00e4ltida v\u00f5idujooksu tingimusi ja andmete rikkumist.<\/p>\n<p>Kokkuv\u00f5ttes on muutumatu objekt objekt, mida ei saa p\u00e4rast loomist muuta.
