// the above method

import java.text.*;

    {

        Optional<Integer> op1
            = Optional.of(456);

        System.out.println("Optional 1: "

        Optional<Integer> op2
            = Optional.of(456);

        System.out.println("Optional 2: "
                           + op2);

        System.out.println("Comparing Optional 1"
                           + " and Optional 2: "
                           + op1.equals(op2));

}

Optional 1: Optional[456]
Optional 2: Optional[456]
Comparing Optional 1 and Optional 2: true
