How do I loop thorough a 2D ArrayList in Java and fill it?

Question

I am trying to use 2D arrayLists in Java. I have the definition:

ArrayList> myList = new ArrayList

        

Answer 1

Use for-each loop, if you are using Java prior 1.5 version.

for(ArrayList row : myList) {

  for(Integer intValue : row) {

     // access "row" for inside arraylist or "intValue" for integer value.

  }

}
