After Initialisation in java pgm



To extend an array after initialisation
 
public class Main
 {
  public static void main(String[] args) 
{
      String[] names = new String[] { "A", "B", "C" };
      String[] extended = new String[5];
      extended[3] = "D";
      extended[4] = "E";
      System.arraycopy(names, 0, extended, 0, names.length);
      for (String str : extended)
{
         System.out.println(str);
      }
   }
}

Result:
