Algorithm: Student Information Management System
1. Define the Student class:
- Create a class named "Student" as an abstract class.
- Include instance variables for student ID, last name, tuition, and student classification.
- Define methods for setting and getting ID, last name, tuition, and classification.
- Declare an abstract method "setTuition" to be implemented in subclasses.
2. Define the UndergraduateStudent class:
- Create a subclass named "UndergraduateStudent" that extends the Student class.
- Define a constant for undergraduate tuition.
- Implement the "setTuition" method to set tuition to the undergraduate rate.
3. Define the GraduateStudent class:
- Create another subclass named "GraduateStudent" that extends the Student class.
- Define a constant for graduate tuition.
- Implement the "setTuition" method to set tuition to the graduate rate.
4. Define the StudentClassification enumeration:
- Create an enumeration type "StudentClassification" to represent different student classifications like FRESHMAN, SOPHOMORE, etc.
5. Implement the StudentDemo2 class:
- Create a class named "StudentDemo2" to demonstrate the system.
- Instantiate an ArrayList to store student objects.
- Create and add instances of UndergraduateStudent and GraduateStudent to the ArrayList.
- Iterate through the ArrayList and display student information, including ID, last name, tuition, and classification.
6. Define the StudentIdGenerator class:
- Create a class named "StudentIdGenerator" to generate unique student IDs.
- Implement the Singleton pattern to ensure a single instance of the generator.
- Provide methods to get the next ID and set the starting ID.
7. Create a manifest file:
- Create a manifest file named "MANIFEST.MF" to specify the main class for the JAR file.
8. Compile the code:
- Compile the Java code using the "javac" command, creating class files in a "bin" directory.
9. Create a JAR file:
- Create a JAR file named "StudentSimulation.jar" using the "jar" command, including the compiled classes and the manifest file.
10. Run the program:
- Execute the program by running "java -jar StudentSimulation.jar" in the command line.
11. The program will execute, displaying the student information on the console.
