Initializing cats

Java Syntax, Level 5, Lesson 7

Resolved

How to initialize the variables to the passed values?

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; int age; int weight; String address; String color; public void initialize(String name){ this.name = name; this.age = 2; this.weight = 8; this.color = "brown"; } public void initialize(String name, int weight, int age){ this.name = name; this.weight = weight; this.age = age; this.color = "white"; } public void initialize(String name, int age){ this.name = name; this.age = age; } public void initialize(int weight, String color){ this.weight = weight; this.color = color; this.age = 9; } public void initialize(int weight, String address, String color){ this.weight = 8; this.address = "a"; this.color = "white"; this.age = 9; } public static void main(String[] args) { } }

The class must have an initialize method that takes a weight, color, and address as arguments, but initializes all variables except the name.

Read last requirement carefully. A constructor should be there with weight, color and address parameters. Order is important here. You've interchanged address and color position.
