Command Line Expense Tracking Application-JAVA

Hello, My name is Mehmet. I am looking for an expert programmer. You will be writing a simple expense tracking application that will work on command line and will be text based. The programming language that you will use is Contra. It is a simple programming language that I wrote while I was writing a book about interpreter construction. Here it is Github repo: [login to view URL] Here is what the application does: It will add expenses to mysql table and show them on the command line as a summary. Here is the table structure and a sample record: ~~~~~~~~~~~~~~~~~~~~~~~~ create table expense ( id int auto_increment primary key not null, amount mediumint, date datetime, location text, city varchar(128), type varchar(128), method varchar(64), currency varchar(16), notes text, insertdate timestamp ); insert into expense (amount, date, location, city, type, method, currency, notes) values ( 100, '2015-06-24', 'My Favorite Fish Restaurant', 'New York', 'Eating Out', 'Debit', 'USD', 'Went out with friends' ); MariaDB [expense]> select id,amount,type,method from expense; +----+--------+------------+--------+ | id | amount | type | method | +----+--------+------------+--------+ | 1 | 100 | Eating Out | Debit | +----+--------+------------+--------+ ~~~~~~~~~~~~~~~~~~~~~~~~ You will keep it as simple as possible. Don't add any extra feature apart from adding expenses and showing them as a summary. The Contra is pretty simple language that it does not have any inline functions for MySQL. So, you need to write new inline functions by yourself by editing the source code of the Contra. I have added inline functions documentation on the attach. Check it out to learn how to add inline functions to Contra. As you guess, I am giving this task to test Contra programming language with a real application. It is not a simple JAVA task. It is more a task for tweaking a simple interpreter. Copy paste and automatic applications will strictly be ignored. Send your time and cost estimation. The applications without time and cost estimation will be ignored as well. Let me know for any questions about the task. Please read the task description carefully before asking questions.
