java使用Robot类在eclipse上实现自动编写代码

 运行时,把输入法关掉，切换成系统自带的输入法即可；

第二个类是自定义的键值Map集合，主要是为了方便输入字符串，有需要的可以自行添加；

主要的代码如下，会创建一个名称为Automaton.java的类，并输出"Hellow Word,I am a skynet"

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;
import java.io.IOException;

public class Hellow {
    public static void main(String[] args) throws AWTException, InterruptedException, IOException {

        // 创建机器人
        Robot robot = new Robot();
        // 设置默认休眠时间
        robot.setAutoDelay(300);

        // 按下alt键
        robot.keyPress(KeyEvent.VK_ALT);
        // 按下shift键
        robot.keyPress(KeyEvent.VK_SHIFT);
        // 按下n键
        robot.keyPress(KeyEvent.VK_N);

        robot.keyRelease(KeyEvent.VK_ALT);
        robot.keyRelease(KeyEvent.VK_SHIFT);
        robot.keyRelease(KeyEvent.VK_N);

        // 连续两次上键
        robot.keyPress(KeyEvent.VK_UP);
        robot.keyRelease(KeyEvent.VK_UP);

        // 按下弹起回车键
        robot.keyPress(KeyEvent.VK_ENTER);
        robot.keyRelease(KeyEvent.VK_ENTER);

        // 设置默认休眠时间20毫秒
        robot.setAutoDelay(20);

 下面是储存键值的map类，只有一些常用的键值，有需要请自行添加

import java.awt.event.KeyEvent;

    static{
        keyMap = new HashMap<String,Integer>();
        //设置map的值
