problem with javac
I have 3 java files. The first is Book.java, then, I have 2 sub classes, ChildrenBook and TechnicalBook. Book is the super Class.
I can compile the Book.java without problems.
But, when I compile ChildrenBook.java and TechnicalBook.java, javac doesn't return the .class files.
What is the problem ?
Can anybody help me, please ?
