javac compiles your code, it doesn't run the compiled code. You should now have a Zoo.class in that same directory. If so, run java Zoo and it'll work. — yshavit
Please read some tutorials. javac compiles the code it doesnot run the code — Sanjeev

Compile it with javac Zoo.java and run it with java Zoo. From the comments :-

Please is there a way to compile and run it at once?

No, Java is both compiled and interpreted.
