we use contains() and Returns true if this list contains the specified element. More formally, returns true if and only if this list contains at least one element e such that (o==null ? e==null : o.equals(e)).
import java.util.ArrayList;
public class ContailsElement {
public static void main(String[] args) {
ArrayList<String> arr = new ArrayList<String>();
// add element in arraylist
arr.add("c");
arr.add("php");
arr.add("html");
arr.add("java");
// print arraylist
System.out.println("arrayList is = " + arr);
/*
* Returns true if this list contains the specified element
*/
System.out.println(arr.contains("php"));
System.out.println(arr.contains("more"));
}
}
Output:
arrayList is = [c, php, html, java]
true
false
