Java基础练习--子类继承

1．写一个Java应用程序，主要是体现父类子类间的继承关系。父类：鸟，子类：麻雀、鸵鸟、鹰。子类继承父类的一些特点，如都是鸟的话就都会有翅膀、两条腿等，但它们各自又有各自的特点，如麻雀的年龄、体重；鸵鸟的身高、奔跑速度；鹰的捕食、飞翔高度等。

package d;

public class Bird {
int leg=2;
int chibang=2;
public void cry(){
	System.out.println("@#$%^%^&*~~");
}

}

	this.age = age;
}

	this.weight = weight;
}

	System.out.println("Maque-cry");
}

	System.out.println(age);
	System.out.println(weight);
}
