Recap - True or False

Part of the Fundamentals section of Coddy's Java journey — lesson 37 of 73.

Challenge

Beginner

Write a program that gets a String input from the user.

The program will output "T" if the input equals "1" and "F" otherwise.

Hint: In Java, use .equals() to compare Strings instead of ==, as == checks reference equality and may not work correctly for String comparison.

Try it yourself

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        // Write your code below

    }
}
