Description
Create a mini java application as following.
→ Create following beans with properties
Address (city, state, pinCode)
Student (id, name, marks, section, Address)
→ Create a Service implementation class having following operations. Use interface for
template and then concrete class service implementation.
addStudent() – This method should add provided student object on collection (choose
the collection as best fit List/LinkedList). Student id should be randomly generated and
method should return it bundled with student object.
deleteStudent() – This should take studentId in input and remove that associated
student object from collection
findStudent() – This method should return student based on provided studentId
findStudentWithPincode() – This method should take city pincode as input and should
return collection of students with that address
sortWithName() – define a method which should return collection of sorted student with respect to name
setOfMarks() – define a method which should return collection of unique marks
obtained by all students (duplicates should be omitted)
addAllStudents() – define a method which should take collection of Student object in
parameter and add them in available collection of students. This method should also
maintain the order of students with respect to obtained marks.
Hint: Use switch-case for performing operations from command line (i.e. press 1 to add
student, 2 for deleting etc.) Use collections sorting, comparator/comparable for object
