写一个java程序,主要是要运用数组,还要体现父类子类间的继承关系。

父类：
public class Bird{
public void sound(){System.out.println("I'm a bird!");}
public void fly(){System.out.println("I can fly!");}
public void body(){System.out.println("I have two wings and two legs!");}
}

麻雀：
public class Sparrow extends Bird{
int age;
int weight;
public void sound(){System.out.println(I'm a sparrow!);}
public void printAge(){System.out.println("My age is "+age);}
public void printWeight(){System.out.println("My weight is "+weight);}
public void setAge(int age){this.age=age;}
public void setWeight(int wight){this.weight=weight;}
}

鸵鸟：
public class Ostrich extends Bird{
int speed;
int height;
public void sound(){System.out.println(I'm a ostrich!);}
public void fly(){Syttem.out.println("I can't fly!");}
public void printSpeed(){System.out.pr
