intern() behaving differently in Java 6 and Java 7

Question

class Test {
    public static void main(String...args) {
        String s1 = \"Good\";
        s1 = s1 + \"morning\";
        System.out.println(s1.intern());
              


        

Answer 1

You need to use s1.equals(s2). Using == with String objects compares the object references themselves.

Edit: When I run your second code snippet, I do not get "both are equal" printed out.

Edit2: Clarified that references are compared when you use '=='.
