You need to fire up the compiler and then run the JVM. Is this what you want? — nhahtdh, Oct 06 '12 at 03:50
Simple java -jar your_jar.jar or javac your_class would work. or you mean something else? — vikas, Oct 06 '12 at 03:53

Yes, the JVM can only run bytecode (.class files). You can pack it into a Jar like Tom said. – LanguagesNamedAfterCofee Oct 06 '12 at 03:58
If you don't want to compile but still use the JVM you need to avoid java and use one of the scripting languages that can run on the JVM such as ruby (jruby), javascript (rhino), groovy... – Tom Oct 06 '12 at 04:06
If you don't have a jar, just do `java Foo` to execute Foo.class – glenn jackman Oct 06 '12 at 13:28
