My problem is making my Main class and Journal class connect together, in the Main class users will input two variables and click the button to create the table, in the Journal class, it will take the two variables and make it go through a process before they get added into the table so i need JTextField1 as variable a and JTextField2 as variable b.
I used netbeans to create the Main class and my own methods to create the table class please help! Thanks! This is the part of the Main class Netbeans tells me to edit when I right click > Events > Action > Action Performed
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
int data1 = Integer.parseInt(jTextField1.getText());
int data2 = Integer.parseInt(jTextField2.getText());
}
Here is my Code:
package Components;

Please help add anything or delete anything in my code to make them work, THANK YOU :)
