Create an ArrayList with type of an object array

Like the title says, I am trying to instantiate an ArrayList with type of a class that I want to be an array. Probably I did not explain it correctly in technical terms, so let's just look at a pseudo code:

List<TestClass[5]> lTestList = new ArrayList<TestClass[5]>();

Where should I specify the size of the TestClass type array? Apologies if my explanation does not make much sense as I am still learning.

List<TestClass[]> lTestList = new ArrayList<TestClass[]>();

You shouldn't specify size of array in generic.

The type of a TestClass array is TestClass[]. So you need to use that as your generic parameter.

List<TestClass[]> lTestList = new ArrayList<TestClass[]>();

Then when you add items to your list, you can add arrays of the appropriate size.

lTestList.add(new TestClass[5]);
