I have no idea what to do. The third initialize method is accepted, but the others aren't.

Question about the task

Initializing cats

Java Syntax, Level 5, Lesson 7

Resolved

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 { private String name; private int age; private int weight; private String address; private String color; public void initialize(String name){ this.name = name; this.weight = weight; this.age = age; this.color = color; } public void initialize(String name, int weight, int age){ this.name = name; this.age = age; this.weight = weight; this.color = color; } public void initialize(String name, int age){ this.name = name; this.age = age; this.weight = weight; this.color = color; } public void initialize(int weight, String color){ this.age = age; this.weight = weight; this.color = color; } public void initialize(int weight, String color, String address){ this.address = address; this.age = age; this.weight = weight; this.color = color; } public static void main(String[] args) { } }

Thanks, this helped. I noticed that the variables that weren't initialized were grayed out and were the ones that needed to be set to something, yet for some reason, this isn't the case for the third method.

Hey can you help me out here. I am stuck with this tried few things still it is not working. package com.codegym.task.task05.task0510; /* Initializing cats */ public class Cat { //write your code here private String name = null; private int weight; private int age; private String color ; private String address = null; public void intialize (String name){ this.name = name; weight = 5; age = 5; color = "Grey"; } public void intialize (String name, int weight, int age){ this.name = name; this.weight = weight; this.age = age; color = "white"; } public void intialize (String name, int age){ this.name = name; this.age = age; weight = 10; color = "Black"; } public void intialize (int weight, String color){ this.weight = weight; this.color = color; age = 6; } public void intialize (int weight, String color, String address){ this.weight = weight; this.color = color; this.address = address; age = 8; } public static void main(String[] args) { } }

Use: "this.something = something;" if 'something' is an argument of a method. In other cases initialize variables with concrete values: public void initialize(int weight, String color){ this.weight = weight; this.color = color; age = 5; }

This was my first time posting a question. It wouldn't submit unless I typed the question in both places.
