Ints contains() function | Guava | Java

Guava’s Ints.contains() returns true if target is present as an element anywhere in array.
Syntax:

public static boolean 
  contains(int[] array, int target)

Parameters: This method accepts following parameters: 

• array: An array of int values, possibly empty.
• target: A primitive int value.

Return Value: This method returns a boolean value. It returns True if array[i] == target for some value of i.
Example 1:

Java

// Java code to show implementation of
// Guava's Ints.contains() method

import com.google.common.primitives.Ints;
import java.util.Arrays;

class GFG {

    // Driver's code
    public static void main(String[] args)
    {

        // Creating an Integer array
        int[] arr = { 5, 4, 3, 2, 1 };

        int target = 3;

        // Using Ints.contains() method to search
        // for an element in the array. The method
        // returns true if element is found, else
        // returns false
        if (Ints.contains(arr, target))
            System.out.println("Target is present"
                               + " in the array");
        else
            System.out.println("Target is not present"
                               + " in the array");
    }
}

Output:

Target is present in the array

Example 2:

Java

// Java code to show implementation of
// Guava's Ints.contains() method

import com.google.common.primitives.Ints;
import java.util.Arrays;

class GFG {

    // Driver's code
    public static void main(String[] args)
    {

        // Creating an Integer array
        int[] arr = { 2, 4, 6, 8, 10 };

        int target = 7;

        // Using Ints.contains() method to search
        // for an element in the array. The method
        // returns true if element is found, else
        // returns false
        if (Ints.contains(arr, target))
            System.out.println("Target is present"
                               + " in the array");
        else
            System.out.println("Target is not present"
                               + " in the array");
    }
}

Output:

Target is not present in the array
