A. Rewrite the given code such that it handles exceptions and the message "Exception handled successfully" should be displayed whether an exception occurs or not for both dividel) and display_namelength() methods. You can only change inside the main function. public class ExceptionTest { public static void main(String[] args) { calculator obj = new calculator(); obj.divide(); obj.display_namelength(); class calculator { String name = null; int numl; int num2; public calculator () { Scanner input = new Scanner (System.in); System.out.println("Enter the first number"); this.numl = input.nextInt(); System.out.println("Enter the second number"); this.num2 = input.nextInt(); } public void divide () { System.out.println(numl / num2); } public void display_namelength() { System.out.println(name.length(); // name object can be null }
