English is not my first language, so sorry if there is a mistake in the grammar.
My question is, I have a database where I have bills, so when the bills are paid, I put a C of cancel in the table. Now, I am trying to do something in java, I want my jtable show me the bills that are not yet paid. I can import everything from the database to the jtable, but, what I need to do is import just the bills that are not paid?
Thanks
assuming you are using JDBC
you should write something like
SELECT * FROM TABLE_NAME WHERE BILL_PAYED <> 'C'

I want to monitor changes that occur in the database. Say, for instance when an item is removed from the database. I want to be able to use an interface to monitor such changes and create an alert of how many no of items are left in the database . Every 5 min or so. Is there any plugin for java, or some kind of interface or something else? I will be grateful for the help.
Best Option Use DDL TRIGGER as it is DB change event meaning
CREATE DDL TRIGGER
ON DB AFTER DELETE AS
"YOUR ACTION STATEMENT" ;

Currently, I can get back a list of users from an Active Directory group but I would like to return more than just their CN/name. How would I do this?
For example, I have an AD group with 20 members. I can get their names but I would also like to return their job title in the output as well.
In fact, you can get their DNs from the group. To get any other attribute, you need to do an additional query (getAttributes) for each member.

I have a string "eur0.99", it can be "eur123.0" or "som0.10", or "0.99usd", or "123.34any" or something like that. How can I simply insert a space between the price and letters without making a huge nasty messy code?
You can use
System.out.println(input.replaceAll("(?<=[A-Za-z])(?=[0-9])|(?<=[0-9])(?=[A-Za-z])", " "));

Good evening,
if I understand your question well, I may advice you to read the "Clean Code " of Robert C.Martin. It is a great agile book, that can help your to divide your code.
Good luck

I've tried to use JList but it didn't work quite right, I couldn't make columns, just rows. Could someone help me?
Try using JTable and do your own research for how to use JTable.
