Introducing two methods to achieve centered display of Java forms

The editor below will bring you two methods of centering a Java form (Example explanation). The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.

The 1st method:

//setSize(300, 200);
pack();
// 得到显示器屏幕的宽、高
int width = Toolkit.getDefaultToolkit().getScreenSize().width;
int height = Toolkit.getDefaultToolkit().getScreenSize().height;
// 得到窗体的宽、高
int windowsWidth = this.getWidth();
int windowsHeight = this.getHeight();
//System.out.println(windowsWidth+","+windowsHeight);
this.setBounds((width - windowsWidth) / 2,(height - windowsHeight) / 2, windowsWidth, windowsHeight);

The 2nd method:

setLocationRelativeTo(null);
