    s1 and s2 are different instances of String objects, so s1==s2 must be false

    Of course they are not the same. A reference is how a variable can access an object stored in memory. A hashcode is some arbitrary value that the hashcode method returns for a particular object. The following code is a valid but not very useful hashcode method.
    public int hashcode() {
        return 0;
    }
