Create a JAVA PROGRAM that allows user to insert, delete, update(SQL statements). Allows the user to use/input select statements, from statements and where statements.

Focus on whether the program can recognise if the user has entered a VALID or an INVALID statement. Such as Select name, From Student.

Implement functionality for EXECUTE command and EXIT command.

PLEASE STRICTLY USE THIS STARTER CODE BELOW:

package identification;

import java.io.*;

import java.util.Scanner;

public class Main

{

public static void main( String args[] )

{

Scanner input = new Scanner(System.in);

Command comm = null;

String information = "";

while(!(comm instanceof ExitCommand))

{

System.out.print(">");

information = input.nextLine();

if(information.contains(";"))

{

String command = information.substring(0,information.indexOf(";"));

comm = Parser.parse(command);

comm.execute();

information = information.substring(information.indexOf(";")+1)

}

}

}

}

CREATETABLE CLASS

package identification;

import java.sql.*;

public class CreateTable implements Command

{

private String tableName;

private String[] columnNameType;

public CreateTable(String input)

{

//parse the string to see if it is valid.

}

public void execute()

{

System.out.println("Valid Create Syntax.");

}

}

COMMAND CLASS

package identification;

public interface Command {

public void execute();

}

EXIT COMMAND

package identification;

public class ExitCommand implements Command {

public void execute()

{

System.out.println("System exiting.");

}

}

CLASS PARSER

package identification;

public class Parser

{

public static Command parse(String userInput)

{

Command result;

if(userInput.equals("exit"))

result = new ExitCommand();

else if(userInput.startsWith("create table"))

result = new CreateTable(userInput);

return result;

}

}

CAN YOU PLEASE FINISH THE CODE FOR THE CLASSES; DELETE, INSERT,UPDATE,DROP TABLE AND SELECT. AND FINISH UP ON THE STARTER CODE, IF THERE IS ANYTHING MISSING.
