Add new features and specifications to the app you developed in Week 10.

1. Develop a class called OnlineUniversity that extends the University class. The new class "is a" university that delivers its courses online.
2. Two new attributes added to the online university:
   1. -URL which is a string that represents the URL of the online university. For example"monash.edu" and "deakin.com.au"
   2. -OnlineAccounts which is an array list of strings that contains the students' accounts for the online university
3. Develop a constructor that accepts the online university attribute (URL) and the university's attributes.
4. Override the addStudent method such that
   1. -It adds the new students to the students' array list (hint: parent class task)
   2. -It creates an online account for the student and adds it to the onlineAccounts array list as demonstrated in the example below:
      1. *take the first two letters from the student's name and add to it three random digits
      2. *Example: If the URL is "monash.edu" and the student name is "Ellen" then the account is "el942@monash.edu".
      3. *Example: If the URL is "monash.edu" and the student name is "Max" then the account is "ma013@monash.edu".
5. Override the toStirng method to print the attributes of the parent and child classes )hint: use super)
6. Update the driver class (main method) to test the new class

This is the code for week 10
