I am working on an assignment and I have to find largest number from an ArrayList using Iterator. I wrote following code.

Code:

		ArrayList <Integer>alist = new ArrayList<Integer>();
		// populating
		alist.add(101);
		alist.add(777);
		alist.add(872);
		alist.add(102);
		alist.add(23);
		
		// finding the largest number in the ArrayList
		Iterator<Integer> it = alist.iterator();
		int max = 0;
		while(it.hasNext())
		{
			if( it.next() > max)
				max =  it.next();
		}
		System.out.println(max);

It compiles fine but the output is not as required.

Output:

Code:

102

Output should be 872. I am not sure what is happening.
Please look into this.

Thanks.
