Java Program to check if two of three boolean values are true
What are boolean Values?
A boolean variable is a variable that can hold one of two values: true or false. These values are often used to represent true/false statements or on/off conditions. Boolean variables are commonly used in control statements, such as in an if statement, to determine the flow of a program based on whether a condition is true or false.
In this Article, we will write a program to check if two of three boolean values are true.
boolean Values:
Boolean variables are often defined using the bool data type in many programming languages.
For example, you might use a boolean variable to represent whether a light switch is on or off. The variable could be named light is On and its value could be true if the light is on, or false if the light is off.
Pseudo code For above Example :
if (isLightOn) {
System.out.println("The light is on.");
} else {
System.out.println("The light is off.");
}
Output: The light is on // if the value is true The light is off // if the value is false
This code will print “The light is on.” if the isLightOn variable is true, and “The light is off.” if it is false.
Program to check if two of three boolean values are true
import java.util.*;
public class Main{
public static void main(String[] args){
// prints true
System.out.println(checkTwoTrue(true, true, true));
// prints true
System.out.println(checkTwoTrue(true, true, false));
// prints false
System.out.println(checkTwoTrue(true, false, false));
// prints false
System.out.println(checkTwoTrue(false, false, false));
}
public static boolean checkTwoTrue(boolean b1, boolean b2, boolean b3){
// check for b1 & b2 for
if (b1 && b2) {
return true;
}
// check for b1 & b3 for
if (b1 && b3) {
return true;
}
// check for b2 & b3 for
if (b2 && b3) {
return true;
}
// false if above 3 if block will not return any value
return false;
}
}
Output: true true false false
This code defines a checkTwoTrue function that takes three boolean values as input and returns true if any of the three possible combinations of two true values is found. If none of the combinations is found, it returns false. The main function tests the checkTwoTrue function with four different input combinations.
