java.lang.String class Example by using equals() method

class StringDemoEq
{
    public static void main(String[] args)
    {
        String s1 = new String(“NAG”);
        String s2 = new String(“nag”);
        String s3 = “nag”;
        String s4 = “NAG”;
        System.out.println(s1.equals(s2));
        System.out.println(s1.equals(s3));
        System.out.println(s1.equals(s4));
        System.out.println(s2.equals(s3));
        System.out.println(s2.equals(s4));
        System.out.println(s3.equals(s4));

    }
}

        System.out.println(d.i);
        System.out.println(d.s);
        System.out.println(d.b);
        System.out.println(d.f);
        System.out.println(d.l);
        System.out.println(d.d);
        System.out.println(d.ch);
