Question

public class A {

    static String s1 = "I am A";

    public static void main(String[] args) {
        String s2 = "I am A";
        System.out.println(s1 == s2);
    }
}

Above program outputs “true”. Both are two different identifiers/objects how the output is “true” ?

My understanding is that the JVM will create different reference for each object, if so how the output is true?

Answer 1

Java manages a String literal pool. It reuses these literals when it can. Therefore the two objects are actually the same String object and == returns true.

I believe this is called string interning
