[RESOLVED] Best way to create a check list?

Hi,

What is the best way to create a checklist in terms of software develpment when there are hundreds of items? I have thought about check boxes although, this would be a hassle in terms for setup everything. This is an example of the type of check list I am talking about.

Hello Nightwalker83,

As requested, I have moved your thread to the Java Forum.

java Code:

package checklistexample2;
