If you can complete what is required for this assignment without my code i will be satisifed with that, what ever is easiest. Thanks
Deliverables group.java, app.java and student.java as requested below Create an application that . Creates 4 students o Build upon the solutions of the previous labs (e.g., using app.java and student.java) o You will need a version of student.java that has a working whatsup method Creates a group o First you have to design the new Java class called group A group has a name A group has 4 students Create a method in group.java that o displays the group name and the name of each student in the group in app.java us.ng the group variable (instance, object) in group.java o display information about what the third student in the group (retrieving information from the student class variables in the group, not from student variables in the app) is up to now (use the whatsUp() method). For instance: "John" is "doing Java" o Pay attention, you have to use a the group variable (instance, object) in app.java o Something like System.out.println( the student is+g1._Explanation / Answer
