Chapter 5, Problem 14RQ

Explanation of Solution

Cartesian join:

  • It is the formal name for multiplying two tables.
  • It is also called as “CROSS JOIN” that returns the result that contains the product of number of rows in the first and second table.
  • If “WHERE” clause is used in “CROSS JOIN” then it works like “INNER JOIN”.

Syntax:

SELECT table_Name1.column_Name1, table_Name2.column_Name2… FROM table_Name1, table_Name2,…;

Performing Cartesian join:

Creating tables:

CREATE TABLE cseitstudent(studentID INT, sname VARCHAR(30), department VARCHAR(5), sem INT);

CREATE TABLE placement(PlacementID INT,StudentID INT, departme...

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!
