This Source code example for Create ArrayList Object and how to manage data in ArrayList and how to get Data from array List

Example code for Java ArrayList
package example.util;
import java.util.ArrayList;
import java.util.Iterator;
public class ArrayListExample {
public void arrayListExample(){
//Create ArrayList Object
ArrayList<String> arrayList=new ArrayList<String>();
//Store and Remove data from ArrayList
arrayList.add(”value1″);
arrayList.add(”value2″);
arrayList.add(”value3″);
String value3=arrayList.remove(2);
System.out.println(”– Example for Get Value from ArrayList –”);
System.out.println(”Get ArrayList value: “+arrayList.get(0));
System.out.println(”Remove ArrayList value: “+value3);
System.out.println(”Contains ArrayList: “+arrayList.contains(”value1″));
System.out.println(”Contains ArrayList: “+arrayList.contains(”value3″));

System.out.println(”– Example for Iterate list from ArrayList –”);
Iterator<String> it=arrayList.iterator();
while(it.hasNext()){
String value=it.next();
System.out.println(”List Iterated  Value: “+value);
}
System.out.println(”– Example for Loop from ArrayList –”);
for (String temp:arrayList){
System.out.println(”For value ArrayList “+temp);
}

}
public static void main (String args[]){
ArrayListExample arryList=new ArrayListExample();
arryList.arrayListExample();
}
}

Running Result
– Example for Get Value from ArrayList –
Get ArrayList value: value1
Remove ArrayList value: value3
Contains ArrayList: true
Contains ArrayList: false
– Example for Iterate list from ArrayList –
List Iterated  Value: value1
List Iterated  Value: value2
– Example for Loop from ArrayList –
For value ArrayList value1
For value ArrayList value2

Note : index of arrayList start from 0
