Question

JAVA: Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters “done” (case-insensitive) for the line of text.

Note: You are not supposed to use any in-build methods to reverse the text.

Example:

Enter a series of strings:

Hello there

Hey

done

the output is:

ereht olleH

yeH

Answer 1

import java.util.Scanner;

public class PrintStringInReverse {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        System.out.println("Enter a series of strings:");
        String s = scan.nextLine();
        while (!(s.equalsIgnoreCase("done"))){
            for(int i = s.length()-1;i>=0;i--){
                System.out.print(s.charAt(i));
            }
            System.out.println();
            s = scan.nextLine();
        }
    }
}
