Regarding sorting of a list object

[yekkala krishna]

Hi,

i want to sort elements of array list.so i written the below code.may i know why its not displaying in ascending order.
List l=new ArrayList();
l.add("100");
l.add("300");
l.add("10");
l.add("20");
l.add("400");
System.out.println(" before sorting"+l);
Collections.sort(l);
System.out.println(" after sorting"+l);

output:
before sorting[100, 300, 10, 20, 400]
after sorting[10, 100, 20, 300, 400]

Your elements are displayed in ascending order. That is the ascending order for Strings.
If you want the numeric ascending order, drop those quotes and add numbers to your list.
