Set the JFrame to the center of the screen in NetBeans

I am developing a java swing desktop application with NetBeans and I want to set the JFrame to the center of the screen.

from the network I understand that I can use

setLocationRelativeTo(null);

to set the frame to the center But I can’t paste the code into the NetBeans IDE because

    frame.pack()
and frame.setVisible()

NetBeans 7 IDE codes are generated and this will prevent code from being entered between these two methods. to get the following:

frame.pack() 
setLocationRelativeTo(null);
frame.setVisible()

Any suggestions to fix the problem.

  • when writing the constructor giving the code below, make your jframe in the center of the screen

    public ProjectWork_jframe() {
initComponents();

Dimension screenSize,frameSize;
int x,y;
screenSize=Toolkit.getDefaultToolkit().getScreenSize();
frameSize=getSize();
x=(screenSize.width-frameSize.width)/2;
y=(screenSize.height-frameSize.height)/2;
setLocation(x, y);
}
