Initializing cats

Java Syntax, Level 5, Lesson 7

Under discussion

I think everything is fine but still not working

Create a Cat class with five initializers:
- Name,
- Name, weight, age
- Name, age (standard weight)
- Weight, color (unknown name, address and age, i.e. a homeless cat)
- Weight, color, address (someone else's pet)

The initializer's job is to make the object valid.
For example, if the weight is unknown, then you need to specify some average weight.
A cat can't weigh nothing.
The same applies to age and color.
But there may or may not be a name (i.e. name might be null).
The same applies to the address (it might be null).

Requirements:

The program must not read data from the keyboard.
The Cat class must have a String variable name.
The Cat class must have an int variable age.
The Cat class must have an int variable weight.
The Cat class must have a String variable address.
The Cat class must have a String variable color.
The class must have an initialize method that takes a name as an argument, but initializes all variables except the address.
The class must have an initialize method that takes a name, weight, and age as arguments, but initializes all variables except the address.
The class must have an initialize method that takes a name and age as arguments, and initializes all variables except the address.
The class must have an initialize method that takes a weight and color as arguments, and initializes all variables except the name and address.
The class must have an initialize method that takes a weight, color, and address as arguments, but initializes all variables except the name.

package com.codegym.task.task05.task0510; /* Initializing cats */ public class Cat { //write your code here String name; String address; String color; int age; int weight; public void initialize(String name){ this.name=name; this.color=color; this.age=age; this.weight=weight; } public void initialize(String name,int weight,int age){ this.name=name; this.weight=weight; this.age=age; this.color=color; } public void initialize(String name,int age){ this.name=name; this.color=color; this.age=age; this.weight=weight; } public void initialize(int weight,String color){ this.color=color; this.age=age; this.weight=weight; } public void initialize(int weight,String color,String address){ this.address=address; this.color=color; this.age=age; this.weight=weight; } public static void main(String[] args) { } }

public void initialize(String name){
         this.name=name;
         this.color=color;
         this.age=age;
         this.weight=weight;
     }

You are passing only one parameter and initializing all other ? Its wrong, you cannot do this. Similar mistakes are there in your other functions also. Read question carefully. It says if age and weight are not supplied, give them some average number. You cannot do this.weight = weight when weight parameter is not supplied to function. Instead take any number and do this.weight = 10(or any number). Same with age. If name and address are not supplied, they can be initialized to null.
