嘿伙计们让这个机器人通过jtextfield3发送消息次数

此外输入不起作用任何帮助谢谢！运行时出错：

Answer 1

试试这个：

public static void sendkeys(String text) {
    try {
        Robot robot = new Robot();
        String lol = text.toUpperCase();
        for(int i=0;i<lol.length();i++) {
            robot.keyPress(Character.getNumericValue(lol.charAt(i)));
        }
    } catch(java.awt.AWTException exc) {
        System.out.println("error");
    }

}

注意robot.keyPress(Character.getNumericValue(lol.charAt(i)))在转到Robot.keyPress(int c)

之前将您的角色转换为int

当您在方法中传递char时，它会自动转换为Character类型，而不是int

类型

Answer 2

编辑：NonSecwitter的答案更简单，可能适用于所有情况，因此这个答案可能是多余的。

问题在于这一行：

robot.keyPress(lol.charAt(i));

您需要将int传递给Robot.keyPress(int)，而不是char s。

要做的最好的事情可能是获得char的{{1}}值：

int

然后将其转换为int c = Character.getNumericValue(lol.charAt(i));常量：

KeyEvent

这会将角色转换为相应的键码，我认为这就是你想要的。说实话，我不确定是否需要第二步。
