Get specific ArrayList item
public static ArrayList mainList = someList;
How can I get a specific item from this ArrayList? mainList[3]?
Solution 1:
As many have already told you:
mainList.get(3);
Be sure to check the ArrayList Javadoc.
Also, be careful with the arrays indices: in Java, the first element is at index 0. So if you are trying to get the third element, your solution would be mainList.get(2);
Solution 2:
Time to familiarize yourself with the ArrayList API and more:
ArrayList at Java 6 API Documentation
For your immediate question:
mainList.get(3);
