Consider the program

import java.util.ArrayList;

public class SearchAnElement {

  public static void main(String[] args) {
    //ArrayList object 
    ArrayList arrList = new ArrayList();

    //adding elements in the list
    arrList.add("100");
    arrList.add("200");
    arrList.add("300");
    arrList.add("400");
    arrList.add("500");

    //searching element "300"
    boolean isFound = arrList.contains("300");
    if (isFound == false)
      System.out.println("Element is not found in the list");
    else
      System.out.println("Element is found in the list");

  }
}
