interface Pet{ public String getName(); public String getColor(); public int getAge(); } class Cat implements Pet{ private String name; private String color; private int age; public Cat(String name, String color,int age){ this.setName(name); this.setColor(color); this.setAge(age); } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getColor() { return color; } public void setColor(String color) { this.color = color; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }; class Doge implements Pet{ private String name; private String color; private int age; public Doge(String name, String color,int age){ this.name=name; this.color=color; this.age=age; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getColor() { return color; } public void setColor(String color) { this.color = color; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }; class PetShop{ private Pet[] pets; private int foot; public PetShop(int len){ if(len>0){ this.pets=new Pet[len]; }else{ this.pets=new Pet[1]; } } public boolean add(Pet pet){ if(this.foot<this.pets.length){ this.pets[this.foot]=pet; this.foot++; return true; }else{ return false; } } public Pet[] search(String keyWord){ Pet p[]=null; int count =0; for(int i=0;i<this.pets.length;i++){ if(this.pets[i]!=null){ if(this.pets[i].getName().indexOf(keyWord)!=-1||this.pets[i].getColor().indexOf(keyWord)!=-1){ count++; } } } p=new Pet[count]; int f=0; for(int i=0;i<this.pets.length;i++){ if(this.pets[i]!=null){ if(this.pets[i].getName().indexOf(keyWord)!=-1||this.pets[i].getColor().indexOf(keyWord)!=-1){ p[f]=this.pets[i]; f++; } } } return p; } }; public class JavaDemo { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub PetShop ps=new PetShop(5); ps.add(new Cat("白猫","白色的",2)); ps.add(new Cat("黑猫","黑色的",3)); ps.add(new Cat("花猫","花色的",3)); ps.add(new Dog("拉布拉多","黄色的",3)); ps.add(new Dog("金毛","黄色的",3)); ps.add(new Dog("黄狗","黑色的",3)); print(ps.search("黑")); } public static void print(Pet p[]){ for(int i=0;i<p.length;i++){ if(p[i]!=null){ System.out.println(p[i].getName()+","+p[i].getColor()+","+p[i].getAge()); } } } }
