Kas ir nemain\u012bgs objekts?<\/h1>\n

Nemain\u012bgs objekts ir objekts, kuru p\u0113c izveido\u0161anas nevar main\u012bt. Citiem v\u0101rdiem sakot, t\u0101 st\u0101vokli nevar main\u012bt p\u0113c t\u0101 instanc\u0113\u0161anas. Jebkur\u0161 m\u0113\u0123in\u0101jums main\u012bt t\u0101 v\u0113rt\u012bbu izraisa jauna objekta izveidi ar atjaunin\u0101to v\u0113rt\u012bbu, atst\u0101jot s\u0101kotn\u0113jo objektu nemain\u012bgu.<\/p>\n

\u0160o j\u0113dzienu bie\u017ei izmanto programm\u0113\u0161anas valodas<\/a> kas atbalsta funkcion\u0101lo programm\u0113\u0161anu, kuras galven\u0101 iez\u012bme ir nemain\u012bgums. Nemain\u012bgi objekti ir noder\u012bgi situ\u0101cij\u0101s, kad objekta st\u0101vokli nedr\u012bkst main\u012bt, piem\u0113ram, daudzpavedienu vid\u0113, kur vienlaic\u012bga piek\u013cuve main\u012bgiem objektiem var izrais\u012bt sac\u012bk\u0161u apst\u0101k\u013cus un rad\u012bt probl\u0113mas. dati<\/a> korupcija.<\/p>\n

Nemain\u012bgiem objektiem ir vair\u0101kas priek\u0161roc\u012bbas sal\u012bdzin\u0101jum\u0101 ar main\u012bgiem objektiem. Pirmk\u0101rt, tie ir aizsarg\u0101ti pret v\u012btn\u0113m, un tos var dro\u0161i koplietot starp v\u012btn\u0113m bez sinhroniz\u0101cijas. Otrk\u0101rt, par tiem ir viegl\u0101k spriest, jo to st\u0101voklis nevar negaid\u012bti main\u012bties. Tre\u0161k\u0101rt, tos var izmantot k\u0101 atsl\u0113gas hash<\/a> tabulas un kopas, jo to hash v\u0113rt\u012bba ir fiks\u0113ta un laika gait\u0101 nemain\u0101s.<\/p>\n

Nemain\u012bgu objektu piem\u0113ri Java<\/a> ietver String, Integer un LocalDate. Kad string objekts ir izveidots, t\u0101 v\u0113rt\u012bbu nevar main\u012bt. Jebkur\u0161 m\u0113\u0123in\u0101jums to main\u012bt noved pie jauna String objekta izveides ar atjaunin\u0101to v\u0113rt\u012bbu. L\u012bdz\u012bgi, ja reiz ir izveidots objekts Integer, t\u0101 v\u0113rt\u012bbu nevar main\u012bt.<\/p>\n

Tom\u0113r nemain\u012bgi objekti nav piem\u0113roti vis\u0101m situ\u0101cij\u0101m. Da\u017eos gad\u012bjumos main\u012bgie objekti ir piem\u0113rot\u0101ki, piem\u0113ram, ja objekta st\u0101voklis ir bie\u017ei j\u0101atjaunina. \u0160\u0101dos gad\u012bjumos ir svar\u012bgi nodro\u0161in\u0101t, lai piek\u013cuve main\u012bgajiem objektiem tiktu sinhroniz\u0113ta, lai nov\u0113rstu sacens\u012bbu apst\u0101k\u013cus un datu boj\u0101\u0161anu.<\/p>\n
