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:
Java
Java
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:
