Java Question

[CrackaLackaZe]

How do you create a simple java program to save a string to a file, exit the program, then run the program again with the string loaded from that file?

 

[agnitrate]

Umm, way to be specific. What are you doing with the string, etc, etc.

That won't even come close to working in java. It won't even point him in the right direction. You might as well have given him the perl solution.

if he understands the concept of programming, it should point him in the right direction

if he doesn't he should have been more specific

It won't point him in the right direction because of basic java io being completely stream based, the lack of needing real file pointers, and cryptic C shortcuts such as "while(!feof(fp))".

If you actually knew what the java solution looked like, you would realize just how useless what you gave him was. The best thing he can do is start reading the Sun introduction to java streams, it will walk him from how to read/write from the keyboard/screen into how to read/write from files (which just happen to be nearly identical).

instead of wasting your time complaining, make yourself useful and offer a suggestion/fix/something

Never heard of constructive criticism?

Look into PrintWriters and Readers, or FileOutputStreams wrapping ObjectOutputStreams and the corresponding FileInputStreams/ObjectInputStreams.

I already gave him the Java IO Tutorial link, a full 14hrs before you offered anything. He'll find knowledge of how java streams work, and code examples that include reading and writing to files there. Did you want me to code the solution or something?
