Homework SourseCreate a Java FX GUI program that allows the user to insert
Create a Java FX GUI program that allows the user to insert data into a SQL database. The goal of this project is to write a basic Java FX GUI database program. The program should have a list component which on launching the program shows the contents of the database. Also the program should present the user with a form of TextFields for capturing data to insert into a database (use the CPU database you created in previous projects). The form should also have a submit button which will attempt to create a new record in the database. The data should be validated first (numbers, text, blank, etc.). If the data is invalid nothing should be inserted into the database and a warning message should be presented to the user via a Label component. If a record is inserted into the database the List should be updated to include the new record. The report needs to be in the following format: Intel Core i7-6700HQ @ 2.60GHz: $1,509.00 Intel Core i7-3770K @ 3.50GHz: $560.50 Intel Core i5-3570K @ 3.40GHz: $477.23 Intel Core i7-4700MQ @ 2.40GHz: $467.40
SQL database: create database intelprocessors; use intelprocessors; show tables; create table computers(id int not null auto_increment primary key, cpuname varchar( 32 ) not null, performance varchar( 32 ) not null, price float); describe computers;
I need to get my code to read and from the SQL database and and then manipulate the database per the instructions above.
This is what I have so far:
