I hava my program working, but it will not display in the JTextArea of the GUI. I believe that I am missing a line of code. However for the life of me I just cannot figure it out. Please Help.
Here is my code:

Thank you for the help!!!

package my.tutoringreport;

import java.text.DecimalFormat;
import javax.swing.JOptionPane;
import javax.swing.JTextArea;

        int timeWageIndex = 0;
        double minimumWage = 6.55;

    /** Creates new form TutoringReportUI */
    public TutoringReportUI() {
       	timeWage = new Double[3][2];
         final int ROWS = 10;
         final int COLUMNS = 30;
	
        initComponents();    }

Edited 5 Years Ago by peter_budo: Keep It Clear - Do wrap your programming code blocks within [code] ... [/code] tags

when doing

System.out.println();

its not supposed to put it in a text area if thats your thinking
