How I can switch data between two frames in java?

Answer 1

you mean get value from Jframe to another :

frame2 f2 = new frame2();
f2.value2.setText(frame1.value1.getText());
f2.setVisible(true);

ps: the values should be "public static"

Answer 2

If you don't want to use the public modifier you should use the getter and setter methods to access your variable from another class.

For example

class MyFrame extends JFrame {

private int value = 777;

//Some operations
...

public void setValue(int v) {
value=v;
}

public int getValue() {
return value;
}

}

You can do this with all variables you want.

PS: The method of Med Imed-Eddine Boucenda is right, but the static modifier is not necessary in his method.

Answer 6

in a Dialog Form I set the variable in the class and when I want to use the variable in my Main Form I have to create a new object of this class and then the variable is null
