CENGAGE MINDTAP 4-Accumulating Totals in a Loop in Java Accumulating Totals in a Loop f Ⓡ 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 1. Ensure the file named LeftOrRight.java is open. 2. Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class. 3. Execute the program by clicking Run and using the data listed above and verify that the output is correct. Grading When you have completed your program, click the Submit…
