Some issues with Java Robot class

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

public class sample
{
    public static void main(String args[]) throws AWTException {

        Robot robot = new Robot();
        WindowElement StopTime = handler.findElementByAutomationID(Timer, "2049");
        handler.click(StopTime);
        handler.setfocus(StopTime);

        int StopTimeMinute = Minute + 8 ;
        String val = "";
        val = String.valueOf(StopTimeMinute);
        sendkeys(val);
    }

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

In the above code, I am getting source not found error if I try to send variable to robot key event method. => 89. Java robot is failing to press key. Can anyone tell me how I can pass variable to Robot.KeyPress(code)?

And whats wrong in the below code? Robot.KeyPress(VK_SHIFT) is working fine but Robot.KeyPress(code) is throwing the below Error.

WRobotPeer.keypress int(line) : not available [native method]
Source not found.

I even tried sending integer as an argument still same issue.

public static void StopMinute(int StopMinute) throws AWTException{
    Robot robot = new Robot();
    robot.delay(20);
    robot.keyPress(StopMinute);
    robot.keyRelease(StopMinute);
}

Can anyone suggest me with this. Robot.KeyPress(Code)

The method getNumericValue() on Character returns a Unicode code point for that character. Character.getNumericValue('A') returns 10 for instance, whereas KeyEvent.VK_A returns the ascii value of 65. The latter value is used for the AWT Robot, not the first.

Instead of itering over val.length(), do val.toCharArray() instead, and iterate over that. And then pass (int)charArray[i] to robot keyPress.
