Creating a Frame : Swing Tutorials
This program shows you how to create a frame in Java Swing
Application. The frame
in java works like the main window where your components (controls) are added to
develop an application. In the Java Swing, top-level windows are represented by
the JFrame class. Java supports the look and
feel and decoration for the frame.
For creating java standalone application you
must provide GUI for a user. The most common way of creating a frame is, using single argument
constructor of the JFrame class. The argument of the constructor is the title of the window or frame.
Other user interface are added by constructing and adding it to the container one by one. The frame initially
are not visible and to make it visible the setVisible(true)
function is called passing the boolean value true. The close button of the frame by default performs the hide operation for
the JFrame. In this example we have changed this behavior to window close
operation by setting the setDefaultCloseOperation()
to EXIT_ON_CLOSE
value.
setSize (400, 400):
Above method sets the size of the frame or window to width (400) and height
(400) pixels.
setVisible(true):
Above method makes the window visible.
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE):
Above code sets the operation of close operation to Exit the application using the System exit method.
Here is the code of the program :
import javax.swing.*;
public class Swing_Create_Frame{
public static void main(String[] args){
JFrame frame = new JFrame("Frame in Java Swing");
frame.setSize(400, 400);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}

I have created a main frame with 2 buttons, New and Close All. When New is clicked, a new frame is to be created titled Frame 1. Subsequent clicks of New will create additional frames, Frame 2, Frame 3, etc. When Close All is clicked in my main frame, all Frame n's are to close. I'm new to Java Swing and cannot seem to find an example on how to perform this in code? I see stuff on internal frames, but that is not what I am attempting to do. Can you help?
