Thread: java newbie help..

Eclipse keeps finding an error in the word Pet. It says "pet cannot be resolved to a type"
Here is my code..THANKS!

woah, you have a ton of Scanner objects which all read in from System.in. You can declare one and simply use it again.

You don't have a Pet class defined (computers are quite dumb and will have no idea or notion of what a Pet is without you specifically defining what it is). Remember, Java is case sensitive, as well as being letter sensitive (don't know quite how to describe this, but the names must match exactly).

For example, the following 3 would all be considered different in Java:

Pet
Pets
pet

Am I supposed to make another class called Pet? Or is there something I have to do it this class? We started this code in school and are supposed to finish it by tomorrow : /

Your class is called pets

You are attempting to do:

Pet pet1 = new Pet(readName1, readAge1, readWeight1);

It should be:

pets pet1 = new pets(readName1, readAge1, readWeight1);

But there will still be issues with readName1, readAge1, readWeight1

You need to create a constructor of pets.

For example:

        public pets(String readName1, int readAge1, double readWeight1) {
