JFrame size is too small

i have created a JFrame in netbeans. But when i run the program, the Jframe size is too small.
here is my code.

import javax.swing.JFrame;

public class Window {

private static void demo()
{
JFrame frame =new JFrame();
frame.setVisible(true);
}
public static void main(String args) {
javax.swing.SwingUtilities.invokeLater(new Runnable(){
public void run()
{
demo();
}
});
}
}


pack()

You can use frame.setSize(width, height) in order to set its size or frame.setBounds(x, y, width, height) for setting both the location and size.

frame.setSize(width, height)

frame.setBounds(x, y, width, height)

A better choice would be to call frame.pack() after you add some components to its content pane.

frame.pack()

Try this way...

Use the setSize(width, height) method of JFrame.

setSize(width, height)

public class Myframe extends JFrame{

public Myframe(){
this.setSize(300,300);
}

public static void main(String args){

EventQueue.invokeLater(new Runnable(){

public void run(){
Myframe f = new Myframe("Frame");
f.setVisible(true);
}
});
}
}


f.visible()

setVisible(true);

If you want to maximize it you could try

this.setVisible(false);
this.setExtendedState(MAXIMIZED_BOTH);
this.setVisible(true);
this.setResizable(false);


Else for some specific size use

this.setSize(width,height);


You just need to add one line line so that you can give your frame a size.The line is

frame.setSize(300,300);


Here is the full code:

import javax.swing.JFrame;

public class Window {

private static void demo()
{
JFrame frame =new JFrame();
frame.setSize(300,300);
frame.setVisible(true);
}
public static void main(String args) {
javax.swing.SwingUtilities.invokeLater(new Runnable(){
public void run()
{
demo();
}
});
}
}


you must have a public components method like:

public gestion_name_of_class (){

initComponents();

}

Cordially.
