How can I get elements from the ArrayList?

Question

I have

private List<Test> tests   = new ArrayList<Test>();

and

void creatingList ()
{
    for (int i = 0; i < 10; i++)
        for (int j = 0; j < 10; j++) {
            if (array[k] == 1)
            {
                Test te = new Test(i, j);
                tests.add(te);
            }
            k++;
        }
}

For example, I have here list of numbers or Strings: (1,0); (1,1); (3,5); (5,5)

How can I get elements at specified position in the List? For example, I need second value from the element included in the 3rd parenthesis.

Answer 1

To get element at specified index in the List one shoud use get(int index) method.

In your case you may want to use: tests.get(2).nameOfTheFieldWhereTheSecondValueIsStored.

It is strongly recommended, to have a glance at documentation before asking a question: http://docs.oracle.com/javase/7/docs/api/java/util/List.html
