Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 3, Size: 1  
  
Please help me ...  
  
class Demo
{
List<List<Double>>list10 =new ArrayList<>();  
List<List<Double>>list10CompWith00 =new ArrayList<>();  
  
 public static void main(String[] args)
{
Demo obj =new Demo();  
obj.arrayToList();  
  
}
void arrayToList()
{
Double[][] arr10 = {{5.25, 4.12, 3.0, 6.0},  
{12.9, 2.09, 4.0, 7.0}};  
 for (Double[] ele : arr10)
{
list10.add(Arrays.asList(ele));  
}
System.out.println("Main List: ");  

for (List<Double> ele:list10)
{
System.out.println(ele);  
}
System.out.println();  
System.out.println("Comp List after adding");  
 for (int i=0; i<list10.size(); i++)
{
list10CompWith00.add(new ArrayList<>());  
 for (int j=0; j<4; j++)
{
if (list10.get(i).get(j)>5.0)
{
list10CompWith00.get(i).add(j, list10.get(i).get(j));  
}

}

}

for (List<Double> ele:list10CompWith00)
{
System.out.println(ele);
