Code:

import java.util.ArrayList;
import java.util.Iterator;

public class LargestNumber {
	public static void main(String[] args){
		ArrayList<Integer> aList = new ArrayList<Integer>();
		aList.add(101);
		aList.add(872);
		aList.add(777);
		aList.add(102);
		aList.add(23);
		
		Iterator<Integer> it = aList.iterator();
		int max = 0;
		while(it.hasNext()){
			int temp = it.next();
			if(temp > max)
				max = temp;
		}	
		System.out.println("Max value:"+max);
	}

}

I think what happens is, only if you call it.next() it goes to the next element and continues iteration. This was something new for me too, i just tried giving a temp variable and it worked!!
