Abstract data type: The data type that is defined by the user which include both data and functions are called abstract data type. The data is the representation of any process and the function is the behavior of data type. Database model: The conceptual view of the database is defined as data management system that contains routine that translate the commands into the actions required by the actual data storage system so that the result is obtained according to the user’s need. This conceptual view of the database is called a database model.

1. Create a Person.java file. Implement the public Person and Student classes in Person.java, including all the variables and methods in the UMLS. Person -name: String -street: String -city: String +Person(String name, String, street, String, city) +getName(): String +setName(String name): void +getStreet(): String +setStreet(String street): void +getCity(): String +setCity(String City): void +toString(): String Student -Id: int +Person(String name, String, street, String, city, int Id) +getId(): int +setId(int Id): void +toString(): String 2. Create a StudentTest.java file. Implement a public StudentTest class with a main method. In the main method, create one student object and print the object using System.out.println(). Your printing result must follow the example output: name: Mike, street: Morris Ave, city: Union, Id: 1000 Hint: You need to modify the toString methods in the Student class and Person class!
