hi..
The string is

String [][] array1 = new String[][]{{"aaaa", "bbbb"},{"aaaa"," cccc"," dddd"," eeee"},{"aaaaa", "fffff", "gggg"}};

I want to display the elements as
aaaa, bbbb
aaaa,cccc
aaaa,dddd
aaaa,eeee
aaaaa,fffff
aaaaa,gggg

The following code

C#

for (int row1=0;row1<=array1.length;row1++){
           for  ( int cols=0 ;cols<array1[row1].length ;cols++){
                      System.out.println(array1[0][0] +" "+ array1[row1][cols+1]);

}

}
gives me output as aaaa bbbb
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2

Please suggest me what I should do to get the prefered output..Any help will be appreciated ...

I think your array specification is wrong for a multidimensional array... Don't you get an error on it? The elements seems ambiguous..
I think example usage should be:
string[,] array2Db = new string[3, 2] { { "one", "two" }, { "three", "four" },
{ "five", "six" } };

Solution 1

You are stepping outside of the array, change it to this;

Java

for (int row1=0;row1<array1.length;row1++) {
   for (int cols=1 ;cols<array1[row1].length ;cols++) {
      System.out.println(array1[0][0] +" "+ array1[row1][cols]);
   }
}
