We would like to know how to add element to the end of a List/in the middle of a List.
import java.util.ArrayList; import java.util.List; /*from w ww . jav a 2 s . c o m*/ public class MainClass { public static void main(String args[]) throws Exception { // Create/fill collection List list = new ArrayList(); list.add("A"); list.add("B"); list.add("C"); System.out.println(list); } }
The code above generates the following result.
in the middle of a List
import java.util.ArrayList; import java.util.List; /* w w w . j a va 2 s .co m*/ public class MainClass { public static void main(String args[]) throws Exception { List list = new ArrayList(); list.add("A"); list.add("B"); list.add("C"); list.add(1, "G"); System.out.println(list); } }
The code above generates the following result.
