The countTrue() method of Booleans Class in Guava Library is used to count the number of values that are true in the specified boolean values passed as the parameter.
Syntax:
public static int countTrue(boolean... values)
Parameters: This method accepts the boolean values among which the true values are to be count.
Return values: This method returns an integer value which is the count of values that are true.
Example-1 :
// Java code to show implementation of// Guava's Booleans.countTrue() method import com.google.common.primitives.Booleans;import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Creating a Boolean array boolean[] arr = { false, true, false, true, true }; // Using Booleans.countTrue() method to // get the number of values that are true System.out.println(Booleans.countTrue(arr)); }} |
Output:
3
Example 2 :
// Java code to show implementation of// Guava's Booleans.countTrue() method import com.google.common.primitives.Booleans;import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Creating a Boolean array boolean[] arr = { false, false, false, false }; // Using Booleans.countTrue() method to // get the number of values that are true System.out.println(Booleans.countTrue(arr)); }} |
Output:
0
