I m using the following loop , but its only typing the first charecter and the rest as numbers, any idea ?
import java.awt.*;
import javax.swing.KeyStroke;
public class test {
public static void main(String[] args) throws AWTException
{
Robot r = new Robot();
String s = "Face";
for (int i = 0; i < s.length(); i++)
{
char res = s.charAt(i);
r.keyPress(res);
r.keyRelease(res);
r.delay(1000);
}
}
}
OUTPUT typing : F135
The keyPress/Release methods need an int value that represents the character you want to type. These value are the key code for each character as determined by the KeyEvent.VK_??? variables.
Try:
import java.awt.*;
import java.util.*;
import java.lang.reflect.Field;
import java.awt.event.*;
import javax.swing.*;
public class RobotCharacter
{
public static void main(String[] args)
throws Exception
{
JTextField textField = new JTextField(10);
JFrame frame = new JFrame();
frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
frame.add( textField );
frame.pack();
frame.setLocationRelativeTo( null );
frame.setVisible( true );
Robot robot = new Robot();
typeCharacter(robot, "a");
typeCharacter(robot, "b");
typeCharacter(robot, "C");
typeCharacter(robot, "D");
}
public static void typeCharacter(Robot robot, String letter)
{
try
{
boolean upperCase = Character.isUpperCase( letter.charAt(0) );
String variableName = "VK_" + letter.toUpperCase();
Class clazz = KeyEvent.class;
Field field = clazz.getField( variableName );
int keyCode = field.getInt(null);
robot.delay(1000);
if (upperCase) robot.keyPress( KeyEvent.VK_SHIFT );
robot.keyPress( keyCode );
robot.keyRelease( keyCode );
if (upperCase) robot.keyRelease( KeyEvent.VK_SHIFT );
}
catch(Exception e)
{
System.out.println(e);
}
}
}
However, even this won't work for all characters. For example on my keyboard the "%" is above the "5". You can't use VK_PERCENT. The key stroke needed is VK_5 along with a shift. There is no way to know the actual mapping of your keyboard to do this automatically.
So a Robot is not a good way to do this.
