Write a java program that prompts user to enter two integer numbers and print the sum. Then, ask the user if he want to do this again. If he answers yes, repeat the input operation and the sum again. Sample Run: Enter a number: 2 Enter another number: 4 The sum is: 6 Do you want to do this again? Y Enter a number: 5 Enter another number: 3 The sum is: 8 Do you want to do this again? N Thank you for using our program. Question Two: Write a java program that does the following: 1- Define a matrix called cat of the size (nx n ). and let the user enters its values by using while loop. 2- Define a one dimension array called lab, so that its size is the number of non-diagonal elements in the previous matrix cat. (2 marks) 3- The array lab entries should be the non-diagonal elements in the previous matrix cat. 4- Print out the third large number of array lab.
