java猫

❶ java创建一个猫类Cat。具体要求如下 急急急在线等

publicclassCat{

privatestaticStringhobby="睡觉";

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+"会爬树，能爬"+height);
}

//省略getter//setter方法.

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

}

publicclassMain{

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

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

//打印猫的信息
System.out.println(catA);
System.out.println(catB);

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

}

❷ java程序 一个主人有两只宠物,一条狗一只猫,狗叫旺财，猫叫小花，分别给宠物喂食

publicclassPerson{
publicstaticvoidmain(Stringargs[]){
Animala1=newAnimal("猫","小花","鱼");
Animala2=newAnimal("狗","旺财"，"骨头");
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);
}
}
//我也才学java不到一个月，我就能理解这么多
//还可以写继承的。亦可以写成多线程的。

//继承就是把Animal类当父类，再写两个类继承它。这里又可以复习多态，哈哈。

//多线程就是同事喂这俩动物。

❸ Java 猫吃鱼狗吃肉

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("鱼");
new Dog().eat("肉");
}

❹ java建立猫cat类和狗类,具备叫声的方法cry(),

/*定义动物父类*/
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);
	}

}
