    String s1 = new String("java-buddy");
    String s2 = new String("java-buddy");
    String s3 = "java-buddy";

    private void CmpString(){
        System.out.println("s1==s2: " + String.valueOf(s1==s2));
        System.out.println("s3==s4: " + String.valueOf(s3==s4));
        System.out.println("s1==s3: " + String.valueOf(s1==s3));
        System.out.println("s3==s5: " + String.valueOf(s3==s5));
        
        System.out.println("s1.equals(s2): " + s1.equals(s2));
        System.out.println("s3.equals(s4): " + s3.equals(s4));
        System.out.println("s1.equals(s3): " + s1.equals(s3));
        System.out.println("s3.equals(s5): " + s3.equals(s5));
