List of Arrays in Java
Firstly, you can't do new List();
it is an interface.
To make a list of int Arrays, do something like this :
List<int[]> myList = new ArrayList<int[]>();
P.S. As per the comment, package for List is java.util.List
and for ArrayList java.util.ArrayList
List<Integer[]> integerList = new ArrayList<Integer[]>();
Use the object instead of the primitive, unless this is before Java 1.5 as it handles the autoboxing automatically.
As far as the sorting goes:
Collections.sort(integerList); //Sort the entire List
and for each array (probably what you want)
for(Integer[] currentArray : integerList)
{
Arrays.sort(currentArray);
}
