JFrame實(shí)現(xiàn)全屏的四種方式，方式一：

import?java.awt.*;?

?

import?javax.swing.*;?

?

public?class?FullScreenDemo1?{?

?

????public?static?void?main(String[]?args)?{?

????????final?JFrame?jframe?=?new?JFrame();?

????????JButton?fullsButton?=?new?JButton("全屏顯示");?

????????JButton?exitButton?=?new?JButton("退出");?

????????exitButton.addActionListener(new?java.awt.event.ActionListener()?{?

????????????public?void?actionPerformed(java.awt.event.ActionEvent?evt)?{?

????????????????System.exit(1);?

????????????}?

????????});?

????????fullsButton.addActionListener(new?java.awt.event.ActionListener()?{?

????????????public?void?actionPerformed(java.awt.event.ActionEvent?evt)?{?

????????????????GraphicsEnvironment?ge?=?GraphicsEnvironment.getLocalGraphicsEnvironment();?

????????????????//通過調(diào)用GraphicsEnvironment的getDefaultScreenDevice方法獲得當(dāng)前的屏幕設(shè)備了?

????????????????GraphicsDevice?gd?=?ge.getDefaultScreenDevice();?

????????????????//?全屏設(shè)置?

????????????????gd.setFullScreenWindow(jframe);?

????????????}?

????????});?

????????jframe.add(fullsButton);?

????????jframe.add(exitButton);?

????????jframe.setLayout(new?FlowLayout());?

????????jframe.setSize(400,?300);?

????????jframe.setVisible(true);?

????}?

}?

方式二：

import?java.awt.FlowLayout;?

?

import?javax.swing.JButton;?

import?javax.swing.JFrame;?

import?javax.swing.UIManager;?

public?class?FullScreenDemo2?{?

?

????public?static?void?main(String[]?args)?{?

????????JFrame?jframe?=?new?JFrame();?

????????JButton?exitButton?=?new?JButton("退出");?

????????exitButton.addActionListener(new?java.awt.event.ActionListener()?{?

????????????public?void?actionPerformed(java.awt.event.ActionEvent?evt)?{?

????????????????System.exit(1);?

????????????}?

????????});?

????????jframe.add(exitButton);?

????????jframe.setLayout(new?FlowLayout());?

????????jframe.setUndecorated(false);?

????????jframe.getGraphicsConfiguration().getDevice()?

????????????????.setFullScreenWindow(jframe);?

????????jframe.setVisible(true);?

????}?

}?

方式三：

import?java.awt.Dimension;?

import?java.awt.FlowLayout;?

import?java.awt.Toolkit;?

?

import?javax.swing.JButton;?

import?javax.swing.JFrame;?

?

public?class?FullScreenDemo3?{?

????public?static?void?main(String[]?args)?{?

????????JFrame?jframe?=?new?JFrame();?

????????JButton?exitButton?=?new?JButton("退出");?

????????exitButton.addActionListener(new?java.awt.event.ActionListener()?{?

????????????public?void?actionPerformed(java.awt.event.ActionEvent?evt)?{?

????????????????System.exit(1);?

????????????}?

????????});?

????????jframe.add(exitButton);?

????????jframe.setLayout(new?FlowLayout());?

????????/**?

?????????*?true無邊框?全屏顯示?

?????????*?false有邊框?全屏顯示?

?????????*/?

????????jframe.setUndecorated(false);?

????????Dimension?d?=?Toolkit.getDefaultToolkit().getScreenSize();?

????????jframe.setSize(d.width,?d.height);?

????????jframe.setVisible(true);?

????}?

}?

方式四：

import?java.awt.Dimension;?

import?java.awt.FlowLayout;?

import?java.awt.Rectangle;?

import?java.awt.Toolkit;?

?

import?javax.swing.JButton;?

import?javax.swing.JFrame;?

public?class?FullScreenDemo3?{?

?

????public?static?void?main(String[]?args)?{?

????????JFrame?jframe?=?new?JFrame();?

????????JButton?exitButton?=?new?JButton("退出");?

????????exitButton.addActionListener(new?java.awt.event.ActionListener()?{?

?

????????????public?void?actionPerformed(java.awt.event.ActionEvent?evt)?{?

????????????????System.exit(1);?

????????????}?

????????});?

????????jframe.add(exitButton);?

????????jframe.setLayout(new?FlowLayout());?

????????/**?

?????????*?true無邊框?全屏顯示?

?????????*?false有邊框?全屏顯示?

?????????*/?

????????jframe.setUndecorated(false);?

????????Dimension?screenSize?=?Toolkit.getDefaultToolkit().getScreenSize();?

????????Rectangle?bounds?=?new?Rectangle(screenSize);?

????????jframe.setBounds(bounds);?

????????jframe.setExtendedState(JFrame.MAXIMIZED_BOTH);?

????????jframe.setVisible(true);?

????}?

}
