Change size of window depending on size of the screen,Java

Question

我想问些什么，因为我不知道。我已经在Java（Netbeans）上编写了一个程序，我想检查窗口的大小。我想根据屏幕的大小进行更改。有什么想法吗？谢谢。

Answer 1

for example..

JFrame frame = new JFrame();
frame.setSize(Toolkit.getDefaultToolkit().getScreenSize());

Answer 2

To get the screen size:

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
double width = screenSize.getWidth();
double height = screenSize.getHeight();

Then, using width and height , set the size of the frame

Answer 3

Take advantage of the frame API:

JFrame frame = new JFrame(...);
frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
