I was working on the wrong assignment, so I hammered this out, it's almost due, and I am having trouble figuring out how to test my program. Eclipse keeps showing errors when trying to figure out how to populate my fields, assuming I have the rest of the program right. We have worked prior to this with keyboard input and this is the first assignment with inheritance.

present errors
toString cannot be resolved or is not a field, and Constructor Person("String") is undefined.

/**Create a class called Vehicle that has the manufacturer’s name (type String), 
number of cylinders in the engine (type int), and owner (type Person given 
below). Then, create a class called Truck that is derived from Vehicle and has 
the following additional properties: the load capacity in tons (type double since 
it may contain a fractional part) and towing capacity in pounds (type int). Be 
sure your class has a reasonable complement of constructors, accessor and muta- 
tor methods, and suitably defined equals and toString methods. Write a pro- 
gram to test all your methods.

Figured it out, needed to save all files, that got rid of the constructor error.

A couple of parenthesis with nothing between them after toString fixed the error there. And if you're thinking of copying my homework, use this for pointers, but do your own, I handed mine in before this reply.
