10int size = animalData.size();
11String[] arr1 = new String[size]; String[] arr2 = new String[size]; 
12String[] arr3 = new String[size]; String[] arr4 = new String[size];
13for(int i=0;i<size;i++)
14{
15    String[] temp = animalData.get(i).split("\t");
16    arr1[i] = temp[0];
17    arr2[i] = temp[1];
18    arr3[i] = temp[2];
19    arr4[i] = temp[3];
