Writing and Reading Files,fit from storing information in a file and retrieving it later. (MineSweeper could store the size of game the player last chose and keep track of the best time for each size.) Java provides an extensive collection of classes and interfaces for dealing with files (and associated objects such as direc

Debugging with Eclipse,computer did exactly what you told it to do, but it didn’t do what you meant. When programming, it pays to remember that a computer is just a construction of silicon and various metals, so it is literally as dumb as a box of rocks. It has no conscious ability to adjust for your errors, as another pe

Video Games,tion but aren’t video games in classic parlance. For example, an old game called BattleZone (which I used to play in college) is a video game. Civilization, in all of its incarnations, is a computer game but not a video game. What’s the difference? Complexity and the skill used to play the game. Vid

Garbage Collection,grow. For very small programs, this constant growth doesn’t matter much. However, even a program of fairly low complexity and scale can quickly chew through a lot of memory. Therefore, most programs really need some kind of garbage collection mechanism.

Recursion,one of their programming tools. I suspect the difficulty stems from two predicaments: having to give up control so that the recursive classes or methods can do their work and not being able to “see” the recursion work (though the debugger can solve the latter problem). Also, the first try at recursi

Generics and Regular Expressions,tching. A generic specifier (also known as a parameter) is a pattern that code must match in order to use a particular block of code (which might be an interface, a class, a method, or other things). Regular Expressions, on the other hand, use patterns to select substrings within strings. In both ca

Writing a User Interface,manage data in such a way that many programs can access that data). So there’s plenty of work to do outside of user interfaces. Still, though, the visible part of the job attracts a lot of people to the profession, and there’s nothing wrong with that.

Writing and Reading XML,he same room. It’s even used (with Cascading Style Sheets) to display information in web browsers. Every company I’ve worked for over the last dozen years, and every application I’ve written (at least those applications more serious and substantial than Minesweeper), has made at least some use of XML.
