How to return different values based on flags (with.Java)

In this article, we learned about How to return different values based on flags (with.Java)

We’re going to learn by solving a coding test problem, doing a retrospective on the problem we solved, and looking at other ways to solve it. Let’s start with the problem.

Problem

Given two integers a, b and a boolean variable flag as parameters, write a solution function that returns a + b if flag is true or a - b if flag is false.

Example input and output

a: -4 b: 7 flag: true result: 3

In other words, since flag is true, it returns a + b = (-4) + 7 = 3.

My solution to the problem

class Solution {
    public int solution(int a, int b, boolean flag) {
        int answer = (flag) ? a+b : a-b;
        return answer;
    }
}

Solution

Utilize the ternary operator to perform the a+b, a-b operations based on the boolean value of flag.
