java貓

❶ java創建一個貓類Cat。具體要求如下 急急急在線等

publicclassCat{

privatestaticStringhobby="睡覺";

privateStringname;

privateintweight;
privateintage;

publicCat(){
this("",0,0);
}

publicCat(Stringname,intweight,intage){
this.name=name;
this.weight=weight;
this.age=age;
}

publicvoidclimbTree(Stringname,intheight){
System.out.println(name+"會爬樹，能爬"+height);
}

//省略getter//setter方法.

@Override
publicStringtoString(){
return"名字："+this.name+"
"+"體重："+this.weight+"
"+"年齡："+this.age;
}

}

publicclassMain{

publicstaticvoidmain(String[]args){
CatcatA=newCat();
CatcatB=newCat("蘭蘭",8,2);

catA.setName("花花");
catA.setWeight(10);
catA.setAge(3);

//列印貓的信息
System.out.println(catA);
System.out.println(catB);

catA.climbTree(catA.getName(),-9999);
catB.climbTree(catB.getName(),99999);
}

}

未測試

❷ java程序 一個主人有兩只寵物,一條狗一隻貓,狗叫旺財，貓叫小花，分別給寵物餵食

publicclassPerson{
publicstaticvoidmain(Stringargs[]){
Animala1=newAnimal("貓","小花","魚");
Animala2=newAnimal("狗","旺財"，"骨頭");
a1.eat();a2.ert();
}
}
classAnimal{
Stringspecies;
StringanimalName;
StringfoodName;
Animal(Stringspecies,StringanimalName,StringfoodName){
this.species=species;
this.animalName=animalName;
this.foodName=foodName;
}

publicvoideat(){
System.out.print("我的"+species+","+animalName+"吃了："+foodName);
}
}
//我也才學java不到一個月，我就能理解這么多
//還可以寫繼承的。亦可以寫成多線程的。

//繼承就是把Animal類當父類，再寫兩個類繼承它。這里又可以復習多態，哈哈。

//多線程就是同事喂這倆動物。

❸ Java 貓吃魚狗吃肉

public class Cat{
public void eat(String fish){
system.out.println("吃" + fish)
}
}
public class Dog{
public void eat(String meat){
system.out.println("吃" + meat)
}
}
main(){
new Cat().eat("魚");
new Dog().eat("肉");
}

❹ java建立貓cat類和狗類,具備叫聲的方法cry(),

/*定義動物父類*/
classAnimal{
	voidcry(){
		System.out.println("Animalcry");
	}
}

classCatextendsAnimal{
	voidcry(){
		System.out.println("catcry");
	}
}

classDogextendsAnimal{
	voidcry(){
		System.out.println("dogcry");
	}
}

publicclassExe2{
	
	publicstaticvoidcry(Animalanimal){
		animal.cry();
	}
	
	publicstaticvoidmain(String[]args){
		Animalanimal=newAnimal();
		cry(animal);
		
		Catcat=newCat();
		cry(cat);
		
		Dogdog=newDog();
		cry(dog);
	}

}
