Using a conditional expression, write a statement that increments numUsers if up

Question

Using a conditional expression, write a statement that increments numUsers if updateDirection is 1, otherwise decrements numUsers. Ex: if numUsers is 8 and updateDirection is 1, numUsers becomes 9; if updateDirection is 0, numUsers becomes 7. Hint: Start with "numUsers = ...".

import java.util.Scanner;

public class UpdateNumberOfUsers {

public static void main (String [] args) {

int numUsers = 0;

int updateDirection = 0;

numUsers = 8;

updateDirection = 1;

/* Your solution goes here */

System.out.println("New value is: " + numUsers);

return;

}

}

Explanation / Answer

import java.util.Scanner;

public class UpdateNumberOfUsers {

public static void main (String [] args) {

int numUsers = 0;

int updateDirection = 0;

numUsers = 8;

updateDirection = 1;

/* Your solution goes here */

if(updateDirection == 1)

numUsers++;

else

numUsers--;

System.out.println("New value is: " + numUsers);
