一·父类  
package Pa\_001;

public class Animal \{  
/\*\*  
\* 父类，动物类  
\* @author  
\*  
\*/

private String type;//种类
    	private char sex;//性别
    	private String addr;//产地
    	private String color;//颜色
    	private String food;//食物
    	private String sound;//声音
    	public Animal() {
    		super();//调到父类object类的构造方法
    		// TODO Auto-generated constructor stub
    	}
    	public Animal(String type, char sex, String addr) {
    		super();
    		this.type = type;
    		this.sex = sex;
    		this.addr = addr;
    	}
    	public Animal(String type, char sex, String addr, String color) {
    		super();
    		this.type = type;
    		this.sex = sex;
    		this.addr = addr;
    		this.color = color;
    	}
    	public String getType() {
    		return type;
    	}
    	public void setType(String type) {
    		this.type = type;
    	}
    	public char getSex() {
    		return sex;
    	}
    	public void setSex(char sex) {
    		this.sex = sex;
    	}
    	public String getAddr() {
    		return addr;
    	}
    	public void setAddr(String addr) {
    		this.addr = addr;
    	}
    	public String getColor() {
    		return color;
    	}
    	public void setColor(String color) {
    		this.color = color;
    	}
    	
    	/**
    	 * 子类，方法的重写（覆盖）
    	 * 1.特征：方法名，参数，返回值必须一致
    	 * 2.子类的修饰符不能比父类的窄
    	 * 3.类超出的异常不能比父类多
    	 */
    	public void breath(){
    		
    	}
    	public void food(){
    		
    	}
    	public void sound(){
    		
    	}
    	public void addr(){
    		
    	}

二。子类  
package Duotai;

public class Dog extends Dongwu \{

public void food()\{  
System.out.println(“骨头”);

\}  
public void sound()\{  
System.out.println(“汪汪”);  
\}  
\}
