Java Program to Check if two of three Boolean variables are true
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
