Example

The following example shows the use of the Java.util.Arraylist.set () method.

Package Com.yiibai;import Java.util.arraylist;public class Arraylistdemo {public   static void Main (string[] args) { c1/>//create an empty ArrayList with an initial capacity      arraylist<integer> arrlist = new arraylist<integer& gt; (5);      Use Add () method to add elements in the list      arrlist.add (n);      Arrlist.add (a);      Arrlist.add (+);      Arrlist.add (a);      Let us print all the elements available in list for      (Integer number:arrlist) {        System.out.println ("number = "+ number);      }      Inserting elment at 3rd position      Arrlist.set (2,55);        Let us print all the elements available in list      System.out.println ("Printing new list:");      for (Integer number:arrlist) {        System.out.println ("number =" + number);}}}    

Let's compile and run the above program, which will produce the following results:

Number = 15Number = 20Number = 25Number = 22Printing new List:number = 15Number = 20Number = 55Number = 22
