Exercise 1: 1. Use the following UML class diagram to create Java classes: Person name: String +Person() +Person(String) +setName(String): void +getName(): String +display(): void +hasSameName(Person); boolean student ID: int Student +Student(String, int) +Student() +setID(int) void +getID(): int +display(): void +isEqual(Student); boolean Note that: Employee salary: double +Employee(String, double) +setSalary(double) : void +getSalary: double +displayO: void a. Method display() in Person prints out the name of the person. b. Method display() in Student prints out the name and the ID of the student. c. Method display() in Employee prints out the name and the salary of the employee. d. Method has SameName(Person) compares the names. e. Method isEqual(Student) compares the names and ID. It should use the method hasSameName(Person). 2. Create a Java program to do the following: a. Read from file information about 10 Students and from another file information about 10 Employees (Hint: use arrays of 20 objects) b. Write code to check if there is a duplicate records of students and print them out C. Write code to check if there is a student and employee who have the same name and print them out. d. Write code to print out the 3 employee with the highest salary Example input files Students file: Saeid 312 Mohammed 124 Salem 751 Nasser 613 Saeed 312 Mohammad 813 Mariam 543 Shamma 712 Naser 784 Salim 751 Example input files Students file: Mansoor 12300 Mohammed 11000 Zayed 7500 Nasser 6900 Saeed 8000 Maryam 8100 Fatema 15000 Asma 7100 Khaled 12800 Khalifah 9600
