You're missing an import statement for FileOutputStream, other than that, I can't spot any errors with this code. I think you'll have to explain a bit more about when you get this error. In what context are you using it?

Go to where the ".class" file is and type the command as java -cp . Abc

A mistake by di2daer.

You're missing an import statement for FileOutputStream.

When we use java.io.*; It means any class/interface of java.io package can be used in our program file without qualify it with java.io package name.
