Question

In my example, I try to get val(0) and val(1) each time.
After for loop I need to save my values to use them for other calculations:

  String[] columns = { "col1" , "col2" }; 
  String[] y = { "TEST", "BUG" ,"ENH" }; 
   List<int[]> values = new ArrayList<int[]>(); 
   for (int j = 0; j < y.length; j++) { 
      // do some actions 
     for(int[] v : values) { 
      //v is the array for one iteration, use it like this: 
       int col1 = v[0]; 
       int col2 = v[1]; 
        values .add(v);
}
}

System.out.prinln(values) =>gives : []

Out of for loop, my values are raised, how do can I do to get my values after for?
Thanks

I don’t understand the question either, but, here’s my best guess at interpreting what the question is trying to do:

String[] columns = {"col1" , "col2"};
String[] y = { "TEST", "BUG" ,"ENH"};
int[][] values = new int[y.length][columns.length]; // 2D array

for (int j = 0; j < y.length; j++) {
  for (k = 0; k < columns.length; k++) {    
    values[j][k] = table.getVal(j, columns[k]);
  }
}
