How to sort List<Integer>?

I have code and I have used list to store data. I want to sort data of it, then is there any way to sort data or shall I have to sort it manually by comparing all data?

import java.util.ArrayList; 
import java.util.List;

public class tes
{
    public static void main(String args[])
    {
        List<Integer> lList = new ArrayList<Integer>();
        lList.add(4);
        lList.add(1);
        lList.add(7);
        lList.add(2);
        lList.add(9);
        lList.add(1);
        lList.add(5);
        for(int i=0; i<lList.size();i++ )
        {
            System.out.println(lList.get(i));
        }
    }
}
