I need to write a Java program that inputs in a list a dog (name and weight) and a cat (name and coat color). Program will stop in put when word Stop is entered.Having issues and some errors. Please help. I have entered comments where my errors are occuring.

import java.util.*;

public class Pet{ 
private String name;
private String type;
private Pet[] pets;

public String getName(){
	return name;
}
public void setName(String name){
	this.name = name;
}
public String getType(){
	return type;
}
public void setType(String type){
	this.type = type;
}
public Pet[] getPets(){
	return pets;
}
public void setPets(Pet[] pets){
	this.pets = pets;
}
public  static void main(String[] args){
	Pet pets = new Pet();
	Pet[] PetArray = new Pet[100];
	int count = 0;
	//insert pets
	while(Type != stop){ //error stop and type can not be resolved
		if //I want it to be if its a dog??
			PetArray[count++] = new Dog(dname, weight);//error "dog can not be resolved to type 
		else // if it is a cat??
		PetArray[count++] = new Cat(cName, cColor); // error cName, cColor resolved as a variable
	}
	
	Scanner scan = new Scanner(System.in);
	System.out.println("Please enter d to add a dog or c to add a cat");
	choice = Keyboard.readChar(); //error choice and Keyboard
	switch(choice){ //error choice
	case 'd':
		System.out.println("You want to add a Dog");
		addDog();
		break;
	case 'c':
	System.out.println("You want to add a Cat");
	addCat();
	break;}
	}
	public static void addDog(){
		if(type==d){ //error on Type
			System.out.println ("Please enter name:  ");
			String dName = Keyboard.readString(); //error on keyboard
			System.out.println("Please enter weight of dog:  ");
			double weight = Keyboard.readdouble(); //error on keyboard
		}
	}
public static void addCat(){
	if(type ==c){ //error on type c
		System.out.println("Please enter name:   ");
		String cName = Keyboard.readString(); //error on keyboard
		System.out.println("Please enter the coat color of the cat:  ");
		String cColor = Keyboard.readString(); //error on keyboard
}
}
}

class Cat extends Pet {
private String coatColor;
public String getCoatColor(){
	return coatColor;
}
public void setCoatColor(String coatColor){
	this.coatColor = coatColor;
}
public Cat(){
	super();
	setType("c");
}
public Cat(String cColor){ //duplicate method
	super();
	setType("c)");
	setCoatColor(cColor);
}
public Cat(String cName){ //duplicate method
	super();
	setType("c");
	setName(cName);
}
class Dog extends Pet{

private double weight;

public double getWeight(){
	return weight;
}
public void setWeight (double weight){
	this.weight = weight;
}
public Dog(double weight){
	super();
	setType("d");
	setWeight(weight);
}
public Dog(){
	super();
	setType("d");}
}

You should implement toString in each class, then print the array
