countTrue.java

This program was created to count the number of how many true boolean values there are.

A boolean cootains two values: true or false.

Function countTrue takes the array of booleans and checks each element to determine if it contains the “true” value. If so, add it to a counter and return it.

The code has been modified slightly and now uploaded to the site.

Code Snippet

public class countTrue{
    public static void main(String[] args){
        boolean[] arr1 = {true, false, false, true, false};
        boolean[] arr2 = {false, false, false, false};
        boolean[] arr3 = {};
        int result = countTrue(arr1);
        int result2 = countTrue(arr2);
        int result3 = countTrue(arr3);
        System.out.println(result);
        System.out.println(result2);
        System.out.println(result3);

    }
    public static int countTrue(boolean[] arr){
        int counter = 0;
        for (int i = 0; i < arr.length; i++){
            if (arr[i] == true){
                counter++;
            }
        }
        return counter;
    }
