    //creating double values
    double x = 5.2;
    double y = -5.2;

    //printing the hexadecimal string for x
    System.out.print("Hexadecimal string for x is: " );
    System.out.println(Double.toHexString(x));    

    //printing the hexadecimal string for y
    System.out.print("Hexadecimal string for y is: " );
    System.out.println(Double.toHexString(y));
