returning an array

[DK]

Is it possible to return a two-dimensional array in a method?

[Sky]

yes...just set the return type as a 2d array instead of the usual int or String in the first line of the method

thanx  :Dfinally got my method to work
silly me, found my error. I put something like return map[][] instead of just return map.

does anyone remember how to output a tab?

i remember it's like \t or /t or something but in what format?

e.g.  System.out.println("blah \t") or whatever?

[gundamf91]

always \n or \t something not something \t

i think......that's right..

[Majin_Blues]

thanks... i hate text output...

if we had more time on this, i woulda started on a GUI

[gundamf91]

actually my prof (today) just showed us something that involved (blahblahblah\t);

so doesn't matter if u put it at the beginning or last (in terms of errors) but i'm sure the order affects the way the stuff is printed out

[Majin_Blues]

order does matter for printing purposes... but not for errors... the hardest thing was formatting text on the screen so it looked nice

do u just type something like
public Arrays methodname(){
   return somearray;
}

but it doesn't work @_@

[bladehunter]

u type:

public (arrayElementType)[][] methodname(){
   return somearray;        ^
}                                   l
                           here, it is 2-D

Ok, I used your suggestion, bladehunter.
public (String)[][] checkGuess (String array [][], blah ....)
{
  //do stuff to array
  return array;
}

and in my main class I have:
array = user.checkGuess (array, blah ...);

but i get an error when I compile ("illegal start of expression").  How do I fix this??

i'm pretty sure you're not supposed to have parentheses around the word String in your header.  

WRONG:
public (String)[][] checkGuess (String array [][], blah ....)

RIGHT:
public String[][] checkGuess ( ...etc.)
