Array of ArrayList in Java example

Array of ArrayList:
Array of ArrayList has to be typecasted first.
ArrayList array has to be initialized first with ArrayList.
Then we have to add the values to the ArrayList.
Iterator has to be created separately for each arraylist of array.

Program:

[java]
import java.util.ArrayList;
import java.util.Iterator;

public class ArrayofArrayList {

public static void main(String[] args) {
ArrayList[] myArrayArrayList = (ArrayList[])new ArrayList[10]; // 10 is the size of the array not arraylist
myArrayArrayList[4] = new ArrayList(); //The array has to be initialized with arraylist
myArrayArrayList[4].add("Nokia");
myArrayArrayList[4].add("Samsung");
myArrayArrayList[4].add("Sony");
myArrayArrayList[4].add("Lg");
myArrayArrayList[4].add("Micromax");
myArrayArrayList[4].add("Ericson");
myArrayArrayList[4].add("Motorola");
myArrayArrayList[4].add("G5");
myArrayArrayList[4].add("G7");
myArrayArrayList[4].add("Karbon");
myArrayArrayList[4].add("Reliance");
Iterator iterArrayArrayList = myArrayArrayList[4].iterator();
while(iterArrayArrayList.hasNext()){
System.out.println(iterArrayArrayList.next());
}

}

}

[/java]

Output:
Nokia
Samsung
Sony
Lg
Micromax
Ericson
