本文介绍了功能相当于C中的" _getch()"在Java中?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我是用C / C乱搞++和最近发现的的_getch()
功能。我最近还得到了一个邀请谷歌Wave(惊人的,顺便说一句),我想效仿发送消息的能力,你竟然打回车键之前。但是,我不知道多少(什么<&LT)。关于C / C ++的网络,虽然我知道在Java中关于它的体面的数额
I was messing around with C/C++ and recently found the _getch()
function. I also recently got an invite to Google Wave (amazing, btw), and I wanted to emulate the ability to send messages before you actually hit the enter key. However, I don't know much (anything <.<) about networking in C/C++, while I know a decent amount about it in Java.
点:
是否有一个Java等同于C函数 _getch()
?

final JFrame frame = new JFrame();
synchronized (frame) {

frame.getRootPane().setWindowDecorationStyle(JRootPane.FRAME);
frame.addKeyListener(new KeyListener() {
@Override
public void keyPressed(KeyEvent e) {
synchronized (frame) {
frame.setVisible(false);
frame.dispose();
frame.notify();
}
}
@Override
public void keyReleased(KeyEvent e) {
}
@Override
public void keyTyped(KeyEvent e) {
}
});
frame.setVisible(true);
try {
frame.wait();
} catch (InterruptedException e1) {
}
}
}
