package com.javarush.task.task05.task0517; /* Конструируем котиков */ public class Cat { String name = null; int age = 3; int weight = 2; String address = null; String color = "red"; public Cat (String name){ this.name = name; this.age = age; this.weight = weight; this.color = color; } public Cat (String name, int weight, int age){ this.name = name; this.age = age; this.weight = weight; this.color = color; } public Cat (String name, int age){ this.name = name; this.age = age; this.weight = weight; this.color = color; } public Cat (int weight, String color){ this.age = age; this.weight = weight; this.color = color; } public Cat (int weight, String color, String address){ this.age = age; this.weight = weight; this.address = address; this.color = color; } //напишите тут ваш код public static void main(String[] args) { } }
