SQL: SQL stands for “Structured Query Language”. The current version of SQL is “ANSI SQL – 92”. It contains constructs which are used to define and process database . They are executed using DBMS-supplied command prompt. 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. Table Creation: Creating table comes under Data Definition Language (DDL). Syntax for creating table is as follows: CREATE TABLE TABLE_NAME ( Column1 datatype, Column2 datatype, … ); DELETE FROM statement: “DELETE FROM” statement is used in order to delete existing records (rows and columns) from the table. Note: It is necessary to use “WHERE” clause when deleting values, because, when it is ignored all the values from the mentioned column name gets deleted. Syntax: DELETE FROM table_Name WHERE condition;

Write a FancyCar class to support basic operations such as drive, add gas, honk horn, and start engine. FancyCar.java is provided with method stubs. Follow each step to gradually complete all methods. Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. The main() method includes basic method calls. Add statements in main() as methods are completed to support development mode testing. Step 0. Declare private fields for miles driven as shown on the odometer (int), gallons of gas in tank (double), miles per gallon or MPG (double), driving capacity (double), and car model (String). Note the provided final variable indicates the gas tank capacity of 14.0 gallons. Step 1 (2 pts). 1) Complete the default constructor by initializing the odometer to five miles, tank is full of gas, miles per gallon is 24.0, and the model is "Old Clunker". 2)…
