Hi. After so many post, you still haven't checked HowToAskQuestionsOnJavaRanch ? First, CarefullyChooseOneForum. I'm moving this thread out of the servlets forum. Then ShowSomeEffort, DoYourOwnHomework and NotACodeMill.

Rajendra Prakash,

I'm guessing you can't just do:

Try using loops (for, while, do/while).

I no good English.

Please refrain from simply handing out a solution of any kind. We want people to learn how to write code themselves, not copy from other people (which is potentially illegal and against every school's code of conduct).

Giving hints is fine, but no actual solutions.

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors

fred, I didn't mean to give away a solution. I presumed, due to square brackets, that an array needs to be printed out. I will try to be more carefull in the future.

Printing an array of arrays and printing a matrix are similar but not exactly the same.
I agree. Here's the link:
