Ints contains() function in Java
The contains() function of the Ints class is used to check whether an element is present in the array or not.
Following is the syntax −
public static boolean contains(int[] arr, int target)
Here, arr is the array wherein the element is to be checked. The target is the element to be checked.
Following is an example to implement the contains() method of the Ints class −
Example
import com.google.common.primitives.Ints;
import java.util.*;
class Demo {
public static void main(String[] args) {
int[] myArr1 = { 100, 150, 230, 300, 400 };
int[] myArr2 = { 450, 550, 700, 800, 1000 };
System.out.println("Array 1 = ");
for(int i=0; i < myArr1.length; i++) {
System.out.println(myArr1[i]);
}
System.out.println("Array 2 = ");
for(int i=0; i < myArr2.length; i++) {
System.out.println(myArr2[i]);
}
int[] arr = Ints.concat(myArr1, myArr2);
System.out.println("Concatenated arrays = "+Arrays.toString(arr));
if (Ints.contains(arr, 800))
System.out.println("Element 800 is in the array!");
else
System.out.println("Element 800 is not in the array!");
}
}Output
Array 1 = 100 150 230 300 400 Array 2 = 450 550 700 800 1000 Concatenated arrays = [100, 150, 230, 300, 400, 450, 550, 700, 800, 1000] Element 800 is in the array!
