how to check if any number is equal in an array java code example

Example 1: Check if an array contains an element java

import java.util.Arrays;

// For String
String[] array = {"Boto", "Nesto", "Lepta"};
String toSearch = "Nesto";

// Inline
if (Arrays.toString(array).contains(toSearch)) {
	// Do something if it's found
}

// Multi line
String strArray = Array.toString(array);
if (strArray.contains(toSearch)) {
	// Do your thing
}

// Different elements
int[] numbers = {1, 2, 3, 4, 5, 6, 7, 8, 9, 0};
int number = 5;

String checker = Arrays.toString(numbers);

// The toString of int in some cases can happen without explicitly saying so
// In this example we convert both
if (checker.contains(Integer.toString(number)) {
	// Found.     
}

Example 2: example to check two integer array are equal in java?

import java.util.Arrays;

public class JavaArrayConceptsConitnue
{
	public static void main(String[] args)
	{
		int[] x = {10,12,20,30,25};
		int[] subx = new int[]{10,12,20,30,26};
		
		if(Arrays.equals(x, subx) == true)
		{
			System.out.println("Both the arrays are equal");
		}
		else
		{
			System.out.println("Arrays are not equal");
		}
	}
}

Example 3: arrays .contains methof

private static final Set<String> VALUES = Set.of(
    "AB","BC","CD","AE"
);
