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();
      }
        });
    }
}

And the output window looks like this.

You must have a public component method like

public gestion_name_of_class() {
    initComponents();
}

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();
  }
    });
}
}

Try this way...

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

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);     
          }
      }); 
    }    
}

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 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.

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