| Oct 16, 2010 at 20:02 | comment | added | andersoj | @WM: You're also coping with some weirdness -- your getTranspose() method is referring directly to the static numbers rather than the argument. | |
| Oct 16, 2010 at 19:59 | comment | added | andersoj | @WM, as pointed out in my answer, you still have a bug in your constructor -- you need this.numbers = ... or you're just setting the argument numbers to something. The NPE probably comes from this. | |

| Oct 16, 2010 at 19:42 | comment | added | W M | but in this way when i run the program it gives me the following: java.lang.NullPointerException:null.... any ideas..?? | |
| Oct 16, 2010 at 16:48 | comment | added | codaddict | yes, you can do that if all your rows have same number of columns. | |
| Oct 16, 2010 at 16:45 | comment | added | W M | as doing that //rows = numbers.length; //colms = numbers[0].length; | |
