Question about the task

Creating cats

Java Syntax, Level 5, Lesson 9

Under discussion

im just really stuck on this task pls help

Create the Cat class with five constructors:
- Name,
- Name, weight, age
- Name, age (standard weight)
- Weight, color (name, address, and age are unknown; the cat is homeless)
- Weight, color, address (someone else's pet)

The constructor'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 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 a constructor that takes a name as an argument, but initializes all variables except the address.
The class must have a constructor that takes a name, weight, and age as arguments, and initializes all variables except the address.
The class must have a constructor that takes a name and age as arguments, and initializes all variables except the address.
The class must have a constructor that takes a weight and color as arguments, and initializes all variables except the name and address.
The class must have a constructor that takes a weight, color, and address as arguments, and initializes all variables except the name.

package com.codegym.task.task05.task0517; /* Creating cats */ public class Cat { String name = null; int weight; int age; String color; String address = null; public Cat(String name){ this.name = "Ellie"; this.age = 13; this.weight = 13; this.color = "red"; } public Cat(String name, int age, int weight){ this.name = "joe"; this.age = 12; this.weight = 231; this.color = "red"; } public Cat(int weight, String address, String color){ this.weight = 12; this.color = "Red"; this.address = "white 1"; this.age = 13; }public Cat(int weight, String color){ this.color = "white"; this.weight = 23; this.age = 13; } public Cat(String name, int age){ this.age = 2; this.name = "Henry"; this.weight = 13; this.color = "red"; } public static void main(String[] args) { } }

1. Do not hardcode values in constructor body, but use the variable arguments from brackets. ie: public Cat(String name){ this.name = name; } 2. Plelase take care of the constructor arguments order as in requirements public Cat(String name, int age, int weight) is not the same as public Cat(String name, int weight, int age)

Example: public class Dog { String name; int age; double weight; String color; } public Dog (String name, double weight) { this.name = name; age = 5; this.weight = weight; color = "white"; }
