机器人类粘贴到putty终端

我正在尝试使用java程序将字符串粘贴到putty命令提示符中 Robot 班级。

为了粘贴,我必须按 shift + insert 钥匙。什么我要做的是将字符串“HelloWorld”粘贴到putty命令提示符。下面是我的代码。

package Auto;

//Related imports

public class Main {

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

        Runtime r = Runtime.getRuntime();
        Process p;

        String username = "ABC";
        String password = "DEF";
        String serverString = "100.0.0.0";

        String s = "C:\\Users\\ib\\Desktop\\Putty\\putty.exe -ssh -l " + username + " -pw " + password + " "
                + serverString + "";
        try {

            p = r.exec(s);

            Thread.sleep(3000);

        } catch (Exception e) {
            System.out.println(e);
            e.printStackTrace();

        }

        String text = "HelloWorld"; 
        StringSelection stringSelection = new StringSelection(text); 
        Clipboard clipboard=Toolkit.getDefaultToolkit().getSystemClipboard();
        clipboard.setContents(stringSelection,stringSelection);

        Robot robot = new Robot();
        robot.keyPress(KeyEvent.VK_SHIFT);
        Thread.sleep(150);
        robot.keyPress(KeyEvent.VK_INSERT); 
    }
}

此代码按 转移 按钮,但不按 插入 按钮。有人能指出我做错了什么吗?

提前谢谢。
