modify the code to get the expected output(shown at the bottom) using constructions provided:

 

change the instance variables representing the number of students and the Student array in the aggregator object to private static variables. change the addStudent method in the aggregator object from an instance method to a static method Remove all initialization/instantiation operations from the aggregator object's default constructor; the constructor can simple be an empty method { } provide a static initializer block in the aggregator object which does the following: o initializes the number of students to 0 o instantiates the student array o adds a single student named "Test Student" to the array using the addStudent method This is the most important part of this assignment, the static initializer block must be included in your submission. The remaining methods (including the main method) in the aggregator object should remain the same. The aggregated Student and Instructor classes should remain the same. Include all three classes in a single Java source code file, do not set the Student or Instuctor class visibility to public, this will keep the compiler happy.

Sample Output (notice the initial student created by the static initializer block):

Instructor = Sally Number of students = 4 Students: [Test Student, Sam, Rajiv, Jennifer, noname, noname, noname, noname, noname, noname]
