Question: I have two JFrames `login.java` and `account.java`   

I need to get the `username` from the `login.java` page and put it in a variable in the `account.java` `JFrame`. How can I do this in the Java NetBeans using the Swing?

Answer: 
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);
    }

```
Well you have very nice way to do it.

Define new Static **Final Objects of that class.**
and Save that value into the Object.

and in other Class u can easily use that objects and as well as that values.
By using 

**CLASSNAME.OBJECT VALUE.**

use that.
