Accumulating Totals in a Loop

Summary

In this lab, you add a loop and the statements that make up the loop body to a Java program that is provided. When completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. Your loop should execute until the user enters the character X instead of L for left-handed or R for right-handed.

The inputs for this program are as follows: R, R, R, L, L, L, R, L, R, R, L, X

Variables have been declared for you, and the input and output statements have been written.

Instructions:

Ensure the file named LeftOrRight. java is open.

Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class.

Execute the program by clicking Run and using the data listed above and verify that the output is correct.

// LeftOrRight. java - This program calculates the total number of left-handed and right-handed

// students in a class.

// Input: L for left-handed; R for right handed; X to quit.

// Output: Prints the number of left-handed students and the number of right-handed students.

import java. util. Scanner;

public class LeftOrRight

{

public static void main(String args[])

{

Scanner s = new Scanner(System. in);

String leftOrRight = ""; // L or R for one student.

int rightTotal = 0; // Number of right-handed students.

int leftTotal = 0; // Number of left-handed students.

// This is the work done in the housekeeping() method

System. out. println("Enter L if you are left-handed, R if you are right-handed or X to quit.");

leftOrRight = s. nextLine();

// This is the work done in the detailLoop() method

// Write your loop here.

// This is the work done in the endOfJob() method

// Output number of left or right-handed students.

System. out. println("Number of left-handed students: " + leftTotal);

System. out. println("Number of right-handed students: " + rightTotal);

System. exit(0);

} // End of main() method.

} // End of LeftOrRight class.
