SQL:

  • SQL stands for “Structured Query Language”.
  • The current version of SQL is “ANSI SQL – 92”.
  • SQL is not a programming language. It is text-based and it is also called as data sublanguage.
    • In order to get SQL as a complete programming language, it should be included in scripting languages like Java, C#, and so on.
  • It contains constructs which are used to define and process database. They are executed using DBMS-supplied command prompt.

    • SQL Server

1. Create a Vehicle.java file. Implement the public Vehicle and Car classes in Vehicle.java, including all the variables and methods in the UMLS. Vehicle - make: String model: String -year: int + Vehicle(String make, String, model, int, year) + getMake(): String + setMake(String make): void + getModel(): String + setModel(String model): void + getYear(): int + set Year(int year): void +toString(): String Car - numDoors: int + numberOfCar: int + Car(String make, String, model, int, year, int numDoors) + getNumDoors(): int + setNumDoors (int num Doors): void + toString(): String 2. Create a CarTest.java file. Implement a public CarTest class with a main method. In the main method, create one Car object and print the object using System.out.println(). Then, print the numberOfCar. Your printing result must follow the example output: make Toyota, model=Camry, year=2022 numDoors=4 1 Hint: You need to modify the toString methods in the Car class and Vehicle class!
