java awt robot

Robot 类用于生成本机系统输入事件，用于测试自动化，自动运行演示和需要鼠标和键盘控制的其他应用程序。 Robot的主要目的是为了方便Java平台实现的自动化测试。

经过封装后的 Robot api 可以现实操作电脑的基本需求

public static void main(String[] args) {
    String outString = "Hello %s";
    for (int i = 0; i < 100; i++) {
        RobotUtils.output(String.format(outString, i));
        RobotUtils.enter();
    }
}
