how to output a variable in java using awt.robot?
ok so i know you can output a using "keyPress(KeyEvent.VK_A)" but is there a way to output a variable?? like:
String str= "hello";
What would the code be to output this?
im sorry, i should have specified: i want to get an input from the user (probably an output screen/system.out/in) then write that into say, an firefox window.... i could click the window, and using robot, type a or whatever, but the best way i can think of to output a String is to have a big if statement with a for loop, is there a better way?

You mean you want to use the Robot class to push each of the keys in order? If so then:
Robot r = new Robot();
for(char c : str.toCharArray()){
r.keyPress(c);
r.keyRelease(c);
}
And in response to the previous answer, yes the Robot class keyPress does serve a purpose more than just to screw a computer... I've used it before for useful purposes.

What do you mean by outputting a variable using Robot?
Robot is for emulating mouse and keyboard events (I personally use it to screw a computer by clicking several hundred times a second) and taking screenshots, but other than that serves no purpose. To output the value of the variable, use System.out.println(), like the common mortal, a drawString() or setLabel() in a GUI or write() to a file for advanced people
