Well, you've to compile it before you try java Subset. This tutorial on creation, compilation and execution of Java source files in command prompt might be of help to you. As a quick update, here's what you can consider doing:

Compiling your code using javac
Once compilation is successful, executing using java command

There is no Subset class in the classpath. Netbeans places the compiled classes in the build directory, so try (as I stated in my comment)...

java -cp build Subset

Make sure you've built via Netbeans. If you haven't, you can also do...

javac -d build src/Subset.java

Try compiling the Subset.java.. For this you will need to go to the directory where your Subset.java is located using Command Prompt, then execute the below commands.

Eg:

javac Subset.java

then,

java Subset
