Check If Two of Three Boolean Variables Are True in Java

In this article, we will understand how to check if two of three Boolean variables are true. Boolean variables are datatypes that can contain only true or false values.

Below is a demonstration of the same −

Input

Suppose our input is −

Input : true, true, false

Output

The desired output would be −

Result : Two of the three variables are true

Algorithm

Step 1 - START
Step 2 - Declare 4 boolean values namely my_input_1, my_input_2, my_input_3 and
my_result
Step 3 - Read the required values from the user/ define the values
Step 4 - Using an if-else condition, compare two of the three values each time using an AND
operator.
Step 5 - Display the result
Step 6 – Stop

Example 1

Here, the input is being entered by the user based on a prompt. You can try this example live in ourcoding ground tool .

import java.util.Scanner;
public class BooleanValues {
   public static void main(String[] args) {
      boolean my_input_1, my_input_2, my_input_3, my_result;
      System.out.println("The required packages have been imported");
      System.out.println("A scanner object has been defined ");
      Scanner my_scanner = new Scanner(System.in);
      System.out.print("Enter the first boolean value: ");
      my_input_1 = my_scanner.nextBoolean();
      System.out.print("Enter the second boolean value: ");
      my_input_2 = my_scanner.nextBoolean();
      System.out.print("Enter the third boolean value: ");
      my_input_3 = my_scanner.nextBoolean();
      if(my_input_1) {
          my_result = my_input_2 || my_input_3;
      } else {
         my_result = my_input_2 && my_input_3;
      }
      if(my_result) {
         System.out.println("Two of the three variables are true");
      } else {
         System.out.println("Two of the three variables are false");
      }
   }
}

Output

The required packages have been imported
A scanner object has been defined
Enter the first boolean value: true
Enter the second boolean value: true
Enter the third boolean value: false
Two of the three variables are true

Example 2

Here, the integer has been previously defined, and its value is accessed and displayed on the console.

public class BooleanValues {
   public static void main(String[] args) {
      boolean my_input_1, my_input_2, my_input_3, my_result;
      my_input_1 = true;
      my_input_2 = true;
      my_input_3 = false;
      System.out.println("The three boolean values are defined as " +my_input_1 +" , " +my_input_2 + " and " +my_input_3);
      if(my_input_1) {
         my_result = my_input_2 || my_input_3;
      } else {
         my_result = my_input_2 && my_input_3;
      }
      if(my_result) {
         System.out.println("Two of the three variables are true");
      } else {
         System.out.println("Two of the three variables are false");
      }
   }
}

Output

The three boolean values are defined as true , true and false
Two of the three variables are true
