3There is no safe way to do this because Java can't control other applications. Yes you might be able to use a Robot, but it is not reliable because you can't guarantee that the Notepad application has focus when you invoke the Robot from Java.camickr– camickr2010-03-20 06:03:42 +00:00Commented Mar 20, 2010 at 6:03

Why dont you save the data in a text file in one app and read from that very text file from your other app?Zak– Zak2010-03-20 06:47:38 +00:00Commented Mar 20, 2010 at 6:47

Yes, using the robot is the solution:
import java.awt.Robot;
import java.awt.event.KeyEvent;
public class Notepad {
static int keyInput[] = { KeyEvent.VK_J, KeyEvent.VK_A, KeyEvent.VK_V,
KeyEvent.VK_A, KeyEvent.VK_SPACE };
public static void main(String[] args) throws Exception {
Runtime.getRuntime().exec("notepad");
Robot robot = new Robot();
for (int i = 0; i < keyInput.length; i++) {
robot.keyPress(keyInput[i]);
robot.delay(100);
}
}
}
if you want to convert a String to keyEvents check this question Convert String to KeyEvents
