Addition of Two Numbers in Java with Error Handling

 Machine Problem in Java

  Write a program using Java to ask the user to give two numbers and then it will compute the sum of the two numbers. If the user will give a character or a letter it will display an error message at asking again the user to give a number in order to compute the sum of the two numbers.
