What is the result of this code? “`java String s1 = new String(“hello”); String s2 = s1.intern(); String s3 = “hello”; System.out.println(s1 == s2); System.out.println(s2 == s3); “`

Accepted Answer

The result of the code is false, true. The `==` operator checks if two references point to the same object. In this case, `s1` and `s2` are different objects, so the first comparison is false. However, `s2` and `s3` both point to the same string literal "hello", making the second comparison true.
