creating Java application

[JavaGuy]

I just finished a Java programming class in high school, but we never did cover how to make Java programs stand on their own. I've checked out books, but they don't help. If it is possible to do make them stand on their own I would really appreciate help. Thxs.

yes, the format is a little different. For example you need to create a main function. I don't remember it anymore since I took java a few years back.......but it surely is possible.

Assuming you are using a unix based system:

Simple source code (I am not a Java programmer, as you will soon be aware)...

public class Foo
{
  public static void main(String[] args)
  {
    System.out.println("get bent");
  }
}

Turn the source into byte code...

Quote:

ed@Slacker:/tmp$ javac Foo.java
ed@Slacker:/tmp$

Et voila!

Quote:

ed@Slacker:/tmp$ java Foo
get bent
ed@Slacker:/tmp$

yes you need a main function that will run the code, and any corresponding classes you wish to run. You will need to compile the class with the main method in it just like any other class too.

If you're using a windows environment and you're NOT using an IDE such as Borland JBuilder or Eclipse, then you'll need to run the programs form a command prompt. For example, to compile a java class in a command prompt window you just type

javac [class_name].java

then to run it its just

java [class name]


Quite simple. Of course, if you are using packages it takes an extra annoying step but its not difficult at all. It seems weird to me that your teacher would teach you how to create a class but not teach you how to properly run that class.

I don't understand what it means to make a java program stand on its own.

basically so you could just run the program like you would a normal .exe file, creosote.
