In Java, What Is The Method To Detect Whether A Specific Value Is Present In An Array?

To determine whether an array contains a particular value in Java, you can use a loop to iterate over the elements of the array and compare each element with the value you are searching for.

Here’s an example code snippet:

public class Main {
    public static void main(String[] args) {
        int[] numbers = {2, 4, 6, 8, 10};

        // Value to search for
        int target = 6;

        // Flag to track if the value is found
        boolean found = false;

        // Iterate over the array elements
        for (int number : numbers) {
            // Check if the element matches the target value
            if (number == target) {
                found = true;
                break;
            }
        }

        // Check if the value was found
        if (found) {
            System.out.println("The value " + target + " is present in the array.");
        } else {
            System.out.println("The value " + target + " is not present in the array.");
        }
    }
}

In this example, the array numbers contains some integers, and we are searching for the value target (which is 6 in this case). The found boolean variable is initially set to false. We iterate over each element of the numbers array using an enhanced for loop and check if the current element matches the target value. If a match is found, we set the found variable to true and break out of the loop. Finally, we check the value of found and display a corresponding message.
