Convert a string to an integer (with.Java)

This is a recap of the “Convert a string to an integer” problem.

We’re going to learn by solving coding test questions, 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 a string n_str consisting of only numbers, it converts n_str to an integer and returns it.

Example input and output

My solution to the problem

class Solution {
    public int solution(String n_str) {
        int answer = Integer.parseInt(n_str);
        return answer;
    }
}

Explanation of the solution

The Integer.parseInt() function was used to return a string as an integer.
