this question has answer here: immutability of strings in java 23 answers i khow java pass-by-value, , when pass object method , change it,it change when out method. can't string object. example: public class text { public void change(string a) { = "ha"; } public static void main(string[] args) { text = new text(); string b = "hi"; a.change(b); system.out.println(b); } } a = "ha"; that statement analogous this: a = new string("ha"); so if string not immutable, you'd have issue pointing a new string object. what happening here "compiler magic" or "syntactic sugar" make easier declare string.
