Question about the task

Creating cats

Java Syntax, Level 5, Lesson 9

Under discussion

I don't understand why that one condition isn't being met. Please help Thanks

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 { //write your code here private String name; private int age; private int weight; private String address; private String color; public Cat(String name){ this.name = name; this.age = 1; this. weight = 1; this.color = "black"; } public Cat(String name, int age, int weight){ this.name = name; this.age = age; this.weight = weight; color = "black"; } public Cat(String name, int age){ this.name = name; this.age = age; this.weight = 1; this.color = "black"; } public Cat(int weight, String color){ this.weight = weight; this.color = color; this.age = 1; } public Cat(int weight, String color, String address){ this.weight = weight; this.color = color; this.address = address; this.age = 1; } public static void main(String[] args) { } }

Hi, this task was trying . i had to be sure i put every requirement in proper order . based on requirements . only using "this." as needed for each class requirement .

public Cat(String name, int weight, int age) {
        this.name = name;
        this.weight = weight;
        this.age = age;
        color = "red";
    }
hope i helped .

Try it with the changed order of weight and age in the parameter list of the constructor. I think the verification depends on the order of these both parameters. Good luck.
