实现如下类之间的继承关系，并编写Music类来测试这些类。
package homework;
public class Instrument
{
public void play()
{
System.out.println("弹奏乐器");
}
}
package homework;
public class Wind
{
public void play()
{
System.out.println("弹奏Wind");
}
public void play2()
{
System.out.println("听，那旋律多美妙");
}
}
package homework;
public class Brass extends Instrument
{
public void play()
{
System.out.println("弹奏Brass");
}
public void play2()
{
System.out.println("听，那节奏感多强烈");
}
}
package homework;
public class Music
{
public static void main(String[] args)
{
Wind w= new Wind();
w.play();
w.play2();
Brass b= new Brass();
b.play();
b.play2();
}
}
