ArrayList Example
FileName:ArrayListDemo.java
import java.util.*;
class ArrayListDemo {
public static void main(String args[]) {
ArrayList al = new ArrayList();
System.out.println(“Initial size of al : “ + al.size());
// add elements to the array list
al.add(“C”); al.add(“A”);
al.add(“E”); al.add(“B”);
al.add(“D”); al.add(“F”); al.add(1, “A2”);
System.out.println(“Size of al after additions : “ +al.size());
// display the array list
System.out.println(“Contents of al: “ + al);
al.remove(“F”);
al.remove(2);
System.out.println(“size of al after deletions: “ + al.size());
System.out.println(“Contents of al: “ + al);
}
}
The output from this program is shown here:
Initial size of al: 0
Size of al after additions: 7
Contents of al: [C, A2, A, E, B, D, F]
Size of al after deletions: 5
Contents of al: [C, A2, E, B, D]
