Unit 3 Java Programming Project

This project is designed for Mr. Hare's APCS-A, focusing on Unit 3 concepts such as conditional statements, Boolean expressions, and logical operators. The project includes a set of methods that students need to implement, along with unit tests to verify their functionality.

Project Structure

• Unit3.java: Contains method headers and task descriptions. Students are required to implement the method bodies.
• Unit3Test.java: JUnit test cases for each method in Unit3.java. These tests validate the correctness of the implemented methods.
• pom.xml: Maven configuration file that manages dependencies and plugins required to build and run the project.

Prerequisites

• Java 17 (or compatible version)
• Maven 3.x

Method Descriptions

Students need to implement the following methods in Unit3.java:

1. isPositive(int number): Returns true if the number is positive, otherwise false.
2. isWithinRange(int number, int lower, int upper): Returns true if the number is within the specified range (inclusive).
3. isLeapYear(int year): Determines if a year is a leap year based on given rules.
4. areBothSameSign(int number1, int number2): Checks if both numbers have the same sign (either positive or negative).
5. containsSubstring(String main, String sub): Returns true if the main string contains the substring and both are not empty.
6. reversePhoneNumber(int phoneNumber): Reverses the given phone number using modulo operations.

Common Mistakes to Avoid

• Using = instead of == in conditionals.
• Ending if statements with a semicolon (;).
• Using multiple if statements when if-else would be more appropriate.
• Misunderstanding the use of logical operators (&&, ||).
• Failing to apply short-circuit evaluation correctly.
