用java多線程寫一個貓叫和狗叫混合的程序 求各位大神指點 本人是it菜鳥級別的

一寫就寫多了，不過包含的東西比較多，java的重要知識點里面也有

這個結(jié)構(gòu)是簡單的處理的，有興趣的話你可以想象下寫成一個小的文字游戲

public class D {

public static void main(String[] args){

Cat cat1 = new Cat("Tom" , 10);

Cat cat2 = new Cat("Sun" , 15 , "蘋果樹");

Dog dog1 = new Dog("lufy" , 5);

Dog dog2 = new Dog("nan" , 20 , "泳池");

cat1.start();

cat2.start();

dog1.start();

dog2.start();

}

}

System.out.println("小貓" + name + "誕生了 , 壽命" + life);

}

@Override

java代碼定義一個animal接口,內(nèi)有shout方法,先返回值類型,再定義三個類,分別實現(xiàn)狗叫聲,貓叫聲,鳥叫聲

interface?animal?{

void?shout();

}

class?Dog?implements?animal{

public?void?shout(){

System.out.println("汪汪叫");

}

}

class?Cat?implements?animal{

public?void?shout(){

System.out.println("喵喵叫");

}

}

class?Bird?implements?animal{

public?void?shout(){

System.out.println("唧唧叫");

}

}

求java抽象類編狗叫的程序

package com.java.basic;

public class AbstractTest {

public static void main(String[] args) {

Dog dog = new Dog();

dog.call();

Cat cat = new Cat();

cat.call();

}

}

/**

* 寵物類

*

* @author Administrator

*

*/

abstract class Pet {

/*

* 叫

*/

abstract void call();

}

/**

* 犬類

*

* @author Administrator

*

*/

class Dog extends Pet {

/*

* 犬類有自己獨特的叫聲

*/

void call() {

System.out.println("汪汪汪!");

}

}

/**

* 貓類

*

* @author Administrator

*

*/

class Cat extends Pet {

/*

* 貓類有自己獨特的叫聲

*/

void call() {

System.out.println("喵喵喵!");

}

}

貓，狗叫JAVA

錯在:

int s;

s=in.readLine();

in.readLine()得到的是String類型,不能直接轉(zhuǎn)化為int,因此要改寫為

int s;

s = Integer.valueOf(in.readLine());

并在函數(shù)聲明出加上throws語句如下:

public static void main(String[] args) throws NumberFormatException, IOException

修改后代碼為.

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

public class jiaojiao implements dog, cat, niu {

public static void main(String[] args) throws NumberFormatException, IOException {

System.out.println("輸入序號以讓各個動物叫,1是狗,2是貓,3是牛");

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

int s;

s = Integer.valueOf(in.readLine());

switch (s) {

case 1:

System.out.print("動物名字" + dog.name + "動物叫聲" + dog.jiao);

;

break;

case 2:

System.out.print("動物名字" + cat.name + "動物叫聲" + cat.jiao);

;

break;

case 3:

System.out.print("動物名字" + niu.name + "動物叫聲" + niu.jiao);

break;

}

}

}

interface animal {

String jiao = " ";

String name = " ";

}

// 狗接口繼承動物的接口

interface dog extends animal {

String jiao = "wangwang";

String name = "dogs";

}

// 貓接口繼承動物的接口

interface cat extends animal {

String jiao = "miaomiao";

String name = "cats";

}

// 牛接口繼承動作的接口

interface niu extends animal {

String jiao = "niuniu";

String name = "nius";

}
