Bytes.contains() method of Guava’s Bytes Class accepts two parameters array and target. The method is used to check if the target element is present in the array or not.
Syntax:
public static boolean contains(byte[] array, byte target)
Parameters: The method accepts two parameters :
- array: An array of byte values, possibly empty.
- target: A primitive byte value which is to be checked if it is present in the array or not.
Return Value: The method returns true if target is present as an element anywhere in array, and returns false if the target is not present anywhere in the array.
Exceptions: The method does not throw any exceptions.
Below examples illustrate the implementation of above method:
Example 1:
// Java code to show implementation of // Guava's Bytes.contains() method import com.google.common.primitives.Bytes; import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Creating a Byte array byte [] arr = { 5 , 4 , 3 , 2 , 1 }; byte target = 3 ; // Using Bytes.contains() method to search // for an element in the array. The method // returns true if element is found, else // returns false if (Bytes.contains(arr, target)) System.out.println( "Target is present" + " in the array" ); else System.out.println( "Target is not present" + " in the array" ); } } |
Target is present in the array
Example 2 :
// Java code to show implementation of // Guava's Bytes.contains() method import com.google.common.primitives.Bytes; import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Creating a Byte array byte [] arr = { 2 , 4 , 6 , 8 , 10 }; byte target = 7 ; // Using Bytes.contains() method to search // for an element in the array. The method // returns true if element is found, else // returns false if (Bytes.contains(arr, target)) System.out.println( "Target is present" + " in the array" ); else System.out.println( "Target is not present" + " in the array" ); } } |
Target is not present in the array
