Algorithm

  1. Read three boolean variables: boolVar1, boolVar2, and boolVar3.

  2. Initialize a counter variable trueCount to 0.

  3. Check if boolVar1 is true:

    • If true, increment trueCount by 1.

  4. Check if boolVar2 is true:

    • If true, increment trueCount by 1.

  5. Check if boolVar3 is true:

    • If true, increment trueCount by 1.

  6. Check if trueCount is greater than or equal to 2:

    • If true, print "At least two out of three variables are true."
    • If false, print "Less than two variables are true."

 

Code Examples

#1 Code Example- Check if two of the three boolean variables are true

Code - Java Programming

// Java Program to check if 2 variables
// among the 3 variables are true

import java.util.Scanner;

class Main {
  public static void main(String[] args) {
    
    // create 3 boolean variables
    boolean first;
    boolean second;
    boolean third;
    boolean result;

    // get boolean input from the user
    Scanner input = new Scanner(System.in);
    System.out.print("Enter first boolean value: ");
    first = input.nextBoolean();

    System.out.print("Enter second boolean value: ");
    second = input.nextBoolean();

    System.out.print("Enter third boolean value: ");
    third = input.nextBoolean();

    // check if two are true
    if(first) {

      // if first is true
      // and one of the second and third is true
      // result will be true
      result = second || third;
    }
    else {

      // if first is false
      // both the second and third should be true
      // so result will be true
      result = second && third;
    }

    if(result) {
      System.out.println("Two boolean variables are true.");
    }
    else {
      System.out.println("Two boolean variables are not true.");
    }

    input.close();
  }
