Answer to Question #251076 in Java | JSP | JSF for Amadix

Question

Create a do-while loop that asks the user to enter two numbers. The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate

Sample Run1

Enter two numbers: 3 15

Do you want another operation: Yes

Enter two numbers: 45 56

Do you want another operation: No

Output1: Sum = 119

Sample Run2

Enter two numbers: 33 150

Do you want another operation: Yes

Enter two numbers: -56 56

Do you want another operation: Yes

Enter two numbers: 58 15

Do you want another operation: Yes

Enter two numbers: 123 87

Do you want another operation: No

Output2: Sum = 466

Answer 1

Answer:

import java.util.Scanner;
public class TestClock {
  public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    int sum = 0;
    char op;
    do{
      System.out.println("Enter two numbers");
      int num1= in.nextInt();
      int num2 = in.nextInt();
      sum = sum+num1+num2;
      System.out.println("Do you wish to perform another operation, Y/N");
      op =in.next().charAt(0);
    }while(op =='Y'||op=='y');
    System.out.println("sum "+sum);
  }
}

Explanation:

The code is implemented in the Java programming language

1. create an integer variable sum
2. create a character variable op
3. create a do-while loop to request the user to enter num1 and num2
4. Request the user to also enter a char Y/N (yes or no respectively)
5. While the char is Y keep adding up the sum and prompt the user to enter two new numbers
6. Else break out of the loop and print the sum
