Store a specific numbers of characters from user input in variables #java

Question

I'm developing a Jframe using the GUI designing tool in NetBeans, as part of my school project.

Say the user inputs "ABCDEFG123456" and presses a button. The program should store characters in the range from 2 to 5 of that string in variable1 and from 7 to the end of the string in variable2.

And the result should be: variable1 = "BCDE" variable2 = "G123456"

Update:

Variables:
1st textarea = ep
rearrange = exe
2nd textarea = output

Can we see some code. Do not be afraid to show us what you have done. :) — gonzo

Very willing to help but as gonzo said please add some code :) would feel better and not writing for you! Hint Hint, look at tutorialspoint.com/java/java_string_substring.htm — basic

I have not written anything, just designed the interface. I just want to know the mechanism to start coding. :) — Sky light

If I understood correctly, your best bet is substring

       public static void main(String args[]){

          String userInput = new String("ABCDEFG123456");

          String variable1 = userInput.substring(1,5);
          String variable2 = userInput.substring(6, userInput.length());

          System.out.println(variable1);
          System.out.println(variable2);

       }

(haven't tested, maybe the indexes are wrong :-) )
