In this tutorial, we will learn how to Search Elements in ArrayList in Java.
ArrayList in Java is a resizable-array implementation of the List interface. ArrayList in Java implements all optional list operations, and permits all elements, including null. In addition to implementing the List interface, this class provides methods to manipulate the size of the array that is used internally to store the list. ArrayList class in Java provides two methods indexOf() and lastIndexOf().
We will use indexOf() and lastIndexOf() methods to search elements in ArrayList in Java. The syntax of indexOf() and lastIndexOf() methods are:
Syntax of indexOf() method:
|
1 |
public int indexOf(Object obj) |
this method returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.
Syntax of lastIndexOf() method:
|
1 |
public int lastIndexOf(Object o) |
this method returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.
Example:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 |
package net.javaforyou.collections; import java.util.ArrayList; public class ArrayListSearchDemo { public static void main(String[] args) { // Create an ArrayList. ArrayList arrayList = new ArrayList<>(); // Add elements to the list. arrayList.add("Apple"); arrayList.add("Mango"); arrayList.add("Banana"); arrayList.add("Guava"); arrayList.add("Orange"); arrayList.add("Avocado"); arrayList.add("JackFruit"); arrayList.add("Guava"); //search an element in the list System.out.println("Index of Orange in the list is : " + arrayList.indexOf("Orange")); //search duplicate element in the list. for duplicate elements indexOf() and lastIndexOf() will return different indexes. System.out.println("First occurrence of Guava in the list is : " + arrayList.indexOf("Guava")); System.out.println("Second occurrence of Guava in the list is : " + arrayList.lastIndexOf("Guava")); } } |
Output:
|
1 2 3 |
Index of Orange in the list is : 4 First occurrence of Guava in the list is : 3 Second occurrence of Guava in the list is : 7 |
Many thanks, Quite a lot of facts.
