Answer 1

Since you have asked how to pass a variable value from one JFrame to Another JFrame (using swing). So for this put one textbox(tx) and a button(jButton3) in login.java and one label(lx) in account.java where we will print the value of the textbox from login.java .

Type this in login.java :-

 private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {                                         
      String msg= tx.getText();
      new NewJFrame2(msg).setVisible(true);
    } 

Then overload constructor in account.java :-

public NewJFrame2(String abc ){
        initComponents();
        lx.setText(abc);
    }
