Question

Newbie question comming up. Trying to get my head around JAVA.

How do I print out the content of the reference and not just their postition ? My program is ment to get some text in from the user, and print it out in a reverse order.

Here is my program (so far):

package myProgram;
import javax.swing.JOptionPane;
public class someRandomClass {
public static void main(String[] args) {
    String word = JOptionPane.showInputDialog("Write som text here");
    StringBuilder outPut = new StringBuilder();
    for (int i = word.length()-1; i>=0; i--){
        outPut.append(i);
    }
    System.out.println(outPut.toString());
  }
}

I am greatfull for any help and tips! 🙂

Answer 1

In the line

 outPut.append(i);

you are appending the value of your loop counter. You surely mean

 outPut.append(word.charAt(i));
