Java：程序在必须收听时关闭

Question

所以我正在尝试“记录”正在按下的键。问题是当我运行我的代码时，程序只是自动停止并将我送回我可以编码的地方。

我使用Eclipse

    import org.jnativehook.keyboard.NativeKeyEvent;
    import org.jnativehook.keyboard.NativeKeyListener;

    public class Listener implements NativeKeyListener {
        public static void main(String[] args) {
            System.out.print("Program started");
        }

        @Override
        public void nativeKeyPressed(NativeKeyEvent arg0) {
            System.out.print("A key was pressed");
        }

        @Override
        public void nativeKeyReleased(NativeKeyEvent arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void nativeKeyTyped(NativeKeyEvent arg0) {
            // TODO Auto-generated method stub

        }   
    }

您需要将侦听器添加到GlobalScreen对象并使程序保持运行。
