Logical operators in Java - Mini Project: Build & Apply

Logical operators

📖 Scenario: You are creating a simple program to check if a person is eligible for a special discount based on their age and membership status.

🎯 Goal: Build a Java program that uses logical operators to decide if a person qualifies for a discount.

📋 What You'll Learn

Create variables for age and membership status

Create a boolean variable for discount eligibility using logical operators

Use if-else to print the eligibility result

💡 Why This Matters

🌍 Real World

Logical operators help decide if conditions are met, like checking eligibility for discounts or access.

💼 Career

Understanding logical operators is essential for writing decision-making code in software development.

1

Create variables for age and membership status

Create an int variable called age and set it to 25. Create a boolean variable called isMember and set it to true.

Java

// Your code here

Need a hint?

Use int for numbers and boolean for true/false values.

2

Create a boolean variable for discount eligibility

Create a boolean variable called eligibleForDiscount that is true if age is greater than or equal to 18 and isMember is true. Use the logical AND operator &&.

Java

int age = 25;
boolean isMember = true;
// Your code here

Need a hint?

Use parentheses to group conditions and && to combine them.

3

Use if-else to print eligibility result

Write an if statement that checks eligibleForDiscount. If true, print "You get a discount!". Otherwise, print "No discount available.".

Java

int age = 25;
boolean isMember = true;
boolean eligibleForDiscount = (age >= 18) && isMember;
// Your code here

Need a hint?

Use if and else blocks to print different messages.

4

Run the program to see the output

Run the program and print the output. The program should print You get a discount!.

Java

int age = 25;
boolean isMember = true;
boolean eligibleForDiscount = (age >= 18) && isMember;
if (eligibleForDiscount) {
    System.out.println("You get a discount!");
} else {
    System.out.println("No discount available.");
}
// Your code here

Need a hint?

Check the console output matches exactly.
