Classes and objects in Java

To create a dog class:

1 /**2 * Dog Class3  * @authorAdministrator4  *5  */6  Public classDog {7String name= "Anonymous";//name8     inthealth=0;//Health Value9     intlove=0;//Degree of intimacyTenString strain= "smart Labrador Retriever";//Variety One      A     /** - * Output Dog information -      */ the      Public voidprint () { -System.out.println ("Pet confession: \ n My Name" + This. name+ ", health value is" + This. health+ ", pro density =" + This. love+ "I am a" + This. strain); -     } -}

To create a penguin class:

1 /**2 * Penguin class, using static constants3  * @authorAdministrator4  *5  */6  Public classPenguin {7String name= "Anonymous";//name8     inthealth=0;//Health Value9     intlove=0;//Degree of intimacyTen     FinalString sex_male= "Q Tsai";  One     FinalString sex_female= "Q sister"; AString Sex=sex_male;//Sex -  -      Public voidprint () { theSystem.out.println ("Pet confession: \ n My Name" + This. name+ ", health value is" + This. health+ ", pro density =" + This. love+ ", I am a" + This. Sex); -     } -}

To create specific pet object information by testing the class:

1 ImportJava.util.*;2  Public classTest {3      Public Static voidMain (string[] args) {4Scanner input=NewScanner (system.in);5System.out.println ("Welcome to the Pet Shop");6System.out.println ("Please enter the name of the pet to be adopted:");7String name=Input.next ();8SYSTEM.OUT.PRINTLN ("Please select the type of pet to adopt: (1. Dog 2. Penguin)");9         intCoolse=input.nextint ();Ten         Switch(coolse) { One          Case1: A             //Choose your dog -SYSTEM.OUT.PRINTLN ("Choose your Dog's breed: (1. Smart Labrador 2. Cool Snow Schnauzer)"); -String strain=NULL; the             if(Input.nextint () ==1) { -strain= "Smart Labrador Dog"; -             } -             Else{ +Strain= "Cool Snow schnauzer"; -             } +             //Create a Dog object and assign a value ADog dog=NewDog (); atDog.name=name; -dog.health=100; -dog.love=100; -dog.strain=strain; - dog.print (); -              Break; in          Case2: -             //Choose Penguin toSYSTEM.OUT.PRINTLN ("Please select Penguin Sex: (1.Q 2.Q sister)"); +String sex=NULL; -             if(Input.nextint () ==1) { thesex= "Q Tsai"; *             } $             Else{Panax Notoginsengsex= "Q Sister"; -             } the             //Create a Penguin object and assign a value +Penguin pg=NewPenguin (); APg.name=name; thepg.sex=sex; +pg.health=100; -pg.love=100; $ pg.print (); $              Break; -         default: -System.out.println ("Please enter the correct option"); the              Break; -         }Wuyi     } the  -}
