The contains() method of Floats Class in Guava library is used to check if a specified value is present in the specified array of float values. The float value to be searched and the float array in which it is to be searched, are both taken as a parameter.
Syntax:
public static boolean contains(float[] array,
float target)
Parameters: This method accepts two mandatory parameters:
- array: which is an array of float values in which the target value is to be searched.
- target: which is the float value to be searched for presence in the array.
Return Value: This method returns a boolean value stating whether the target float value is present in the specified float array. It returns True if the target value is present in the array. Else it returns False.
Below programs illustrate the use of contains() method:
Example 1:
// Java code to show implementation of// Guava's Floats.contains() method import com.google.common.primitives.Floats;import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Creating a Float array float[] arr = { 5.2f, 4.2f, 3.4f, 2.3f, 1.5f }; float target = 3.4f; // Using Floats.contains() method to search // for an element in the array. The method // returns true if element is found, else // returns false if (Floats.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 code to show implementation of// Guava's Floats.contains() method import com.google.common.primitives.Floats;import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Creating a Float array float[] arr = { 2.3f, 4.4f, 6.5f, 8.6f, 10.7f }; float target = 7.5f; // Using Floats.contains() method to search // for an element in the array. The method // returns true if element is found, else // returns false if (Floats.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
