Question

I set an array of integer like below

int[] a = new int[11111];
 //if I set
a[0] = 1;
a[1] = 2;
a[2] = 3;
a[3] = 4;

I want a method such that it gives me
4 but 11111.
Is there any method which I can use?

You should look into using an ArrayList

ArrayList<Integer> myList=new ArrayList<Integer>();
myList.add(1);
myList.add(2);
myList.add(3);

System.out.println("Size:"+myList.size());
