在Windows 10中,将JFrame移动到第二个显示器的最佳方法是什么

通过使用解决问题 setLocationRelativeTo ,则, setUndecorated 和 setExtendedState(JFrame.MAXIMIZED_BOTH) 检查以下内容:

import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;

import javax.swing.JFrame;
import javax.swing.JLabel;

public class DualMonitor {

    public static void main(String... args) {
        GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
        GraphicsDevice[] gs = ge.getScreenDevices();

        javax.swing.JOptionPane.showConfirmDialog((java.awt.Component) null, "Found : " + gs.length, "screen detected ?",
                javax.swing.JOptionPane.DEFAULT_OPTION);

        for (int j = 0; j < gs.length; j++) {
            GraphicsDevice gd = gs[j];
            JFrame dualview = new JFrame(gd.getDefaultConfiguration());

            JFrame frame = new JFrame();
            frame.setLocationRelativeTo(dualview);
            dualview.dispose();

            frame.setUndecorated(true);
            frame.setTitle("I'm on monitor #" + j);
            frame.setSize(400, 200);
            frame.add(new JLabel("hello world"));
            frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
            frame.setVisible(true);

        }
    }
}
