我修改了@ Joseph-gordon的答案，以允許在不強(qiáng)制全屏的情況下實(shí)現(xiàn)此目的：
public static void showOnScreen( int screen, JFrame frame ) {
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gd = ge.getScreenDevices();
if( screen > -1 && screen < gd.length ) {
frame.setLocation(gd[screen].getDefaultConfiguration().getBounds().x, frame.getY());
} else if( gd.length > 0 ) {
frame.setLocation(gd[0].getDefaultConfiguration().getBounds().x, frame.getY());
} else {
throw new RuntimeException( "No Screens Found" );
}
}
在這段代碼中，我假設(shè)getDefaultConfiguration()永遠(yuǎn)不會(huì)返回null。如果不是這種情況，請(qǐng)有人糾正我。但是，此代碼可將您JFrame移至所需的屏幕。

閱讀屏幕2上有關(guān)JFrame.setLocationRelativeTo的文檔后，一種更清潔的解決方案
public void moveToScreen() {
setVisible(false);
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] screens = ge.getScreenDevices();
int n = screens.length;
for (int i = 0; i < n; i++) {
if (screens[i].getIDstring().contentEquals(settings.getScreen())) {
JFrame dummy = new JFrame(screens[i].getDefaultConfiguration());
setLocationRelativeTo(dummy);
dummy.dispose();
}
}
setVisible(true);
}
此功能可用于在屏幕之間切換應(yīng)用程序窗口
