Output of the program :
package com.hubberspot.arraylist;
import java.util.ArrayList;
import java.util.List;
public class ArrayListContainsDemo {
public static void main(String[] args) {
// Create a ArrayList object which can store
// collection of String objects
List< String > stringList = new ArrayList< String >();
// Add few String objects to it
stringList.add("Neha");
stringList.add("Abhishek");
stringList.add("Deepali");
stringList.add("Snehal");
stringList.add("Vijay");
stringList.add("Aditya");
// Lets create an String object and check
// whether ArrayList created above contains it
String name = "Neha";
// In order to check whether ArrayList contains an element
// or not we use list's contains(), which
// Returns true if this list contains the specified element.
if( stringList.contains(name) ) {
System.out.println("The list contains the element : " + name);
}
else {
System.out.println("The list does not contains the element : " + name);
}
name = "Dhwani";
if( stringList.contains(name) ) {
System.out.println("The list contains the element : " + name);
}
else {
System.out.println("The list does not contains the element : " + name);
}
}
}
