Just to add to this:
1) Follow the naming conventions. Only class definitions begin with capital letters. the rest of the variables are accepted to use camel case.
Here's a sample of what you should do to split your stuff up. I'll be very surprised if you can't figure out what the issues are at this point.
Remember
- everything must be in between a class definition (its opening and closing braces).
- a package declaration, if present, must be the first thing that appears in a java file.
- a java file must be named to match the top level (or first public class) being defined
Code:
public class DVD {
private ? indentedVariable;
private ? indentedVariableNumberTwo;
...
} Code:
/* This is a big hint that dvdExt is not a meaningful name. no one knows what the heck a dvdExt will do or why it extends a DVD with a name like that. */
public class AMeaningfulClassDescription extends DVD {
private ? indentedVariable;
private ? indentedVariableNumberTwo;
public void indentedMethod {
}
} Code:
/* Again, think here. what is an Inventory3. why the 3? */
public class Inventory3 {
/* a bunch of indented stuff goes here*/
} Code:
/* Again, think here. what is an Inventory4. why the 4? */
public class Inventory4 {
/* a bunch of indented stuff goes here*/
}
