1.1 Check if a String Array contains a certain value “A”. StringArrayExample1.java package com.mkyong.core; import java.util.Arrays; import java.util.List; public class StringArrayExample1 { public static void main(String[] args) { String[] alphabet = new String[]{"A", "B", "C"}...
The array must be sorted, ifArrays.binarySearch()method is used. In this case, the array is not sorted, therefore, it should not be used. Actually, if you need to check if a value is contained in some array/collection efficiently, a sorted list or tree can do it inO(log(n))or has...
If your array is sorted, you can use the Arrays binarySearch() method to check if the array contains the given value or not.String[] vowels = { "A", "I", "E", "O", "U" }; System.out.println("Unsorted Array = " + Arrays.toString(vowels)); Arrays.parallelSort(vowels); System....
First, let’s check if the array contains one single value. 3.1. Using theanyFunction Kotlin has predefined theany()extension functionon theArrayclass. We can pass a predicate function to theany()function, and theany()function walks through elements in the array and returnstrueonce an element...
Learn how to check if an arraylist contains a value in Java with example. Also, learn to check if array contains an element along with index of element.

We can also usestring find() functionto check if string contains a substring or not. This function returns the first index position where substring is found, else returns -1. str1='I love Python Programming'str2='Python'str3='Java'index=str1.find(str2)ifindex!=-1:print(f'"{str1}"...
