Moving data from an array to a JTable

Question

Hi,
I am facing some problems with handling array data to JTable.
My objective is moving data from a 10X5 data array to a JTable.
I am using the following code:
String columnNames = { "Col 1", "Col 2", "Col 3", "Col 4", "Col 5" };
for(int j=0; j<10; j++)
data[ j ] = array1[ j ] + array2[ j ] + array3[ j ] + array4[ j ] + array5[ j ];
JTable table = new JTable( data, coulmnNames);
Can you please help me with the error in tha above code.My array1 is a String array and the other four arrays are of Integer data type.
Thanks!!!

4 errors
My code segment with line no goes as follows:
private static JTable createTable() {         
       String[] columnNames = { "Col 1", "Col 2", "Col 3", "Col 4"' "Col 5" };
         Object data [ ] [ ] = new Object [10] [5];
   for( int j=0; j<10; j++)
          data [j] [0] = array1[j]; ...................Line:144
          data [j] [1] = array2[j]; ..................Line 145
          data [j] [2] = array3[j]; ....................Line 146
          data [j] [3] = array4[j]; .................Line 147
          data [j] [4] = array5[j];
  final JTable table = new JTable(data, columnNames);
  return table;
[code/]
Array 1 is declared as String array and Array 2,3,4,5 are declared as Integer arrays.The error is coming from the Integer arrays only.
Java version running on my machine is: 1.4.2
Please help!!!
Thanks!!!
