i am writng a program dat will generate 12 x 12 time table and i am using 2 dimensional array,i read in one of the wrox books that when one index is fied and the other varys then it generates column and if it is the other way round then rows are generated,but in my own case the whole thing came out as column,ie
1x1=1
1x2=2 etc,what can i do to make it in row and column

To create a two dimensional array u should declare the array as like this

int twoDimen[][] = new twoDimen[3][3];

This will create 3*3 integer type array.Go ahead.thanks.

Wrong !! declaration.. it should be

int twoDimen[][] = new int[3][3];

Or int[][] twoDimen = new int[3][3];

Java takes both forms.

What they said in the book is correct and they are talking about traversing.
