[问与答] 关于 String#intern

发表于

public Class Example{ public static void main(String[] args) { String s = new String("1"); s.intern(); String s2 = "1"; System.out.println(s == s2);

String s3 = new String("1") + new String("1");
s3.intern();
String s4 = "11";
System.out.println(s3 == s4);

} }

这段代码的我机器上输出结果是 false false.但我看到原文 https://tech.meituan.com/2014/03/06/in-depth-understanding-string-intern.html 的结果是 false true.所以到底结果应该是什么?
