the following code is centered around data collection, filtering, and using the Singleton pattern in Java, which is all part of a mockup "student information management system", with its purpose being making mockup new student accounts. I've been having issues using the software “dbeaver” for making java projects.

-----------------------------
Algorithm: Student Information Management System
1. Create an empty ArrayList to store student objects.
2. Create a StringBuilder to build the student information output.
3. Set the starting ID for student generation using the StudentIdGenerator Singleton.
4. Create four student objects:
a. Create an UndergraduateStudent object "Harry Potter" with the following details:
- Name: Harry Potter
- Student Classification: FRESHMAN
- Address: Atlanta, Georgia, 30305, Main St, 123, Apt 101
b. Create an UndergraduateStudent object "Diana-Wonder-Woman Prince" with the following details:
- Name: Diana-Wonder-Woman Prince
- Student Classification: JUNIOR
- Address: Washington D.C., District of Columbia, 30318, Broadway Ave, 456, Apt 202
c. Create a GraduateStudent object "John Doe" with the following details:
- Name: John Doe
- Student Classification: MASTERS
- Address: New York, New York, 10001, 5th Ave, 789, Apt 303
d. Create a GraduateStudent object "Jane Smith" with the following details:
- Name: Jane Smith
- Student Classification: DOCTORATE
- Address: Los Angeles, California, 90001, Sunset Blvd, 987, Apt 505
5. Loop through each student in the ArrayList:
a. Build student information as follows:
- Name
- ID
- Tuition
- Address (City, State, Zip, Street, Street Number, Apartment Number)
- Student Classification (Undergraduate or Graduate)
b. Print the student information.
6. End the loop.
7. End the program.
