Invalid Name for Java?

Im trying to import a normal wolf model from blockbench and it tells me my model name or whatever is wrong in the file, I know its a common problem because I've looked it up everywhere but cant find a solution that works for me, I'm modding for 1.12.2 and heres the code of the model.

// Made with Blockbench 3.7.1
// Exported for Minecraft version 1.12
// Paste this class into your mod and generate all required imports

public class geometry.wolf extends ModelBase {
    private final ModelRenderer head;
    private final ModelRenderer body;
    private final ModelRenderer upperBody;
    private final ModelRenderer leg0;
    private final ModelRenderer leg1;
    private final ModelRenderer leg2;
    private final ModelRenderer leg3;
    private final ModelRenderer tail;
