3.java基础之关键字instanceof

1. instanceof

使用：对象引用名 instanceof 类名
作用：来判读引用的对象和类名是否兼容（是否继承该类，或爷爷辈的类）
例子：

Team team = new Team();
team.addMember(new Magicer("jwnming",6));
team.addMember(new Soldier("dogee",4));
team.addMember(new Magicer("wanggl",7));
System.out.print("\n" + "团队成员:");
for(int i = 0;i < team.allRole.length;i++){
if (team.allRole[i] instanceof Role ) {
System.out.print(team.allRole[i].getName() + "  ");
}
}
System.out.println("\n" + "\n" +"这个团队的总伤害值:" + team.attackSum());
