Table: The table is constructed with rows and columns. Table contains a group of related records. Column represents a field and row represents a record. Field is the information of a single item. Record is a collection of related fields; it contains all the necessary information of the specific object. In a relation all the columns are filled with their respective value but in a table even though it is a single cell, it is filled with the multiple value. Therefore, a table is not considered as a relation.

Program Plan Intro

Table:

The table is constructed with rows and columns.

Table contains a group of related records.

Column represents a field and row represents a record.

Field is the information of a single item.

Record is a collection of related fields; it contains all the necessary information of the specific object.

In a relation all the columns are filled with their respective value but in a table even though it is a single cell, it is filled with the multiple value.

Therefore, a table is not considered as a relation.

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!
