Send A String To Keyboard Output

Question

Hello, i've come to a stop in my project as i cannot figure out how to send a whole string to the "Keypress".
The simple code to print single letters is easy but does not support multiple lettering or a string. Is there another method or away round this? Also, the clipboard method cannot be used as it is not supported by my application.
Thank you.

We don't need StringBuffer class. String class makes all things.
You can clear unused methods or fields as you need.
