How to compile in Eclipse so I can use outside? (without opening eclipse)

I searched for an answer but didn't found it, so here it goes.

When I try to execute the program from cmd (with javac, I guess), I get this error: 

D:\Libraries\workspace\bucky\bin\bucky>java apples
         Exception in thread "main" java.lang.NoClassDefFoundError: apples (wrong name:bucky/apples)
    at java.lang.ClassLoader.defineClass1(Native Method)
    at java.lang.ClassLoader.defineClass(Unknown Source)
    at java.security.SecureClassLoader.defineClass(Unknown Source)
    at java.net.URLClassLoader.defineClass(Unknown Source)
    at java.net.URLClassLoader.access$100(Unknown Source)
    at java.net.URLClassLoader$1.run(Unknown Source)
    at java.net.URLClassLoader$1.run(Unknown Source)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source)

I wanted to be able to send the application to my friends. I'm very new to this, so if it's a stupid question, it's because I only started a few days ago. I'm using java.util.Locale and java.util.Scanner if that is important. If I need to past the code, tell me. It's about 130 lines.

Thanks (If you noticed, I'm learning on Youtube, "thenewboston" is the user that made the turorials)

That should be really simple. Eclipse got an export dialog. I think it was at File -> Export. There you can choose you desination for your compiled JAR and which external JARS should be inlcuded (e. g. JDBC).

You should post how you try to run your code and the error message here as text. Just copy and paste from the Windows cmd box -- easy to do:

right click cmd window -> click select all -> press enter

and now it's copied to the clipboard.

It looks like you may be trying to run this without taking packages into consideration.

i.e., from the bin subdirectory, call `

otherDirectories/bin>java bucky.apples

But more importantly, if this were my project I'd have Eclipse export it first as a runnable jar file, and then simply run the jar file.

The menu order is:

Right-click on Project -> Export -> Java -> Runnable Jar File
