Code compiles but fails to run (works in NetBeans)

[swilliams236]

I have a basic GUI program that works fine in NetBeans but when I try and run in outside of NetBeans I get the following error...

D:\Java II\BlueJTest>"C:\program files\java\jdk1.7.0\jre\bin\java" multioptioncalc.java
Error: Could not find or load main class multioptioncalc.java

I have a basic GUI program that works fine in NetBeans but when I try and run in outside of NetBeans I get the following error...

D:\Java II\BlueJTest>"C:\program files\java\jdk1.7.0\jre\bin\java" multioptioncalc.java
Error: Could not find or load main class multioptioncalc.java

You can't run .java source code; you have to run your (compiled) class like this:

D:\Java II\BlueJTest>"C:\program files\java\jdk1.7.0\jre\bin\java" multioptioncalc

kind regards,

Jos
