java编程做这个题综合运用继承，多态 集合 来做下面的问题

1.public abstract class Bing {
private String bingType;
public Bing(String bingType)
{
this.bingType=bingType;
}
public String getType()
{
return bingType;
}
abstract void atract();
}
class QiBing extends Bing{
public QiBing(String bingType) {
super(bingType);
}
@Override
void atract() {
System.out.println(this.getType()+"骑马拿刀砍人");
}
}
class BuiBing extends Bing{
public BuiBing(String bingType) {
super(bingType);
}
@Override
void atract() {
System.out.println(this.getType()+"拿刀砍人");
}
}
class GongBing extends Bing{
public GongBing(String bingType) {
super(bingType);
}
@Override
void atract() {
System.out.println(this.getType()+"拿剑射人");
}
}
interface Signal{
public void SendSignal();
}
class JuGuan extends Bing implements Signal{
public JuGuan(String bingType) {
super(bingType);
}
@Override
public void SendSignal() {
System.out.println("军官开始发进攻信号了");
}
@Override
void atract() {

}
}
