Convert to String (with.Java)

This is a post about the “Convert to String” problem.

We’re going to learn about it by solving coding test problems, reflecting on the problems we solved, and exploring other ways to solve them.

Let’s start with the problem.

Problem

Complete the solution function so that, given an integer n, it converts n to a string and returns it.

Example input and output

My solution to the problem

class Solution {
    public String solution(int n) {
        String answer = String.valueOf(n);
        return answer;
    }
}

Explanation of the solution

We used the String.valueOf function, which converts an integer datatype to a string datatype, and returned the value in answer.
