Solution

Hi, Please find my implementation.

Please let me know in case of any issue.

########### Robot.java ##################

public class Robot {

   private String name;

/*

Sample run:

Enter name: PRavesh Kumar

Enter energy: -5

Energy can not be less than zero!!

Enter energy: -11

Energy can not be less than zero!!

Enter energy: 5

name=\'PRavesh Kumar\', energy=5
