You can the java.awt.Windowclass. A Windowis like a JFrame, but with no borders.
你可以java.awt.Window上课。AWindow类似于 a JFrame，但没有边界。
Note that the Windowclass constructor needs a Frame(java.awt.Frame) as an argument, but you can set it to null. You can also extend the Windowclass to customize it like this:
请注意，Window类构造函数需要一个Frame( java.awt.Frame) 作为参数，但您可以将其设置为null. 您还可以扩展Window该类以自定义它，如下所示：
public class MyWindow extends Window{
public MyWindow(){
super(null); // creates a window with no Frame as owner
setBounds(x, y, width, height);
setVisible(true);
}
}
In main, you can create an instance of MyWindowinstead of Window.
在 中main，您可以创建一个MyWindow代替 的实例Window。
public static void main (String[] args) {
Window window = new MyWindow();
// Other stuff in main
}
I hope this helps!
我希望这有帮助！

This code Explains how you can achieve it.
此代码解释了如何实现它。
Note: setUndecorated(true); statement in the constructor.
注意：setUndecorated(true); 构造函数中的语句。
You cannot undecorate the Frame while it is already displayed.
当框架已经显示时，您不能取消装饰框架。
public class MyFrame extends JFrame {
private JPanel contentPane;
private JTextField textField;
/**
* Launch the application.
*/
public static void main(String[] args) {
MyFrame frame = new MyFrame();
frame.setVisible(true);
}
/**
* Create the frame.
*/
public MyFrame() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
contentPane = new JPanel();
contentPane.setBackground(Color.ORANGE);
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
/* important Statement */
setUndecorated(true);
}
}
}

Use method frame.getContentPane(); this method return inside content of any frame. But you need to cast it into a JPanel. PrintUI using JPanel not JFrame....
使用方法 frame.getContentPane(); 此方法返回任何框架的内部内容。但是您需要将其转换为 JPanel。PrintUI 使用 JPanel 而不是 JFrame ....

Inside the constructor you can put code setUndecorated(true) it will disappear Frame.
在构造函数中，您可以放置代码 setUndecorated(true) 它将消失 Frame。
For example: //This is constructor
例如：//这是构造函数
public freak() {
super("Images");
panel = new JPanel();
ImageIcon image = new ImageIcon("C:\Users\shilu.shilu-PC\Desktop\2.jpg");
label = new JLabel(image);
add(panel);
add(label);
//Main thing is this one
setUndecorated(true);
//Just add this code in your constructor
}
