public static void main(String[] args) {

  p.generate();
  p.show(p.ts);
}
}
class player/* implements Comparator*/{
int money;
int wood;
int sin;
int death;
int whole;
player(int money,int wood,int sin,int death){
  this.money=money;
  this.wood=wood;
  this.sin=sin;
  this.death=death;
  whole=money+wood+sin+death;
}
public void show(){
  System.out.print("金币:"+money+'\t');
  System.out.print("木材:"+wood+'\t');
  System.out.print("罪恶值:"+sin+'\t');
  System.out.print("死亡数:"+death+'\t');
  System.out.println("总分:"+whole);
}
/*public int compare(Object o1, Object o2) {
  player p1=(player)o1;
  player p2=(player)o2;
  return p1.whole<p2.whole?1:p1.whole<p2.whole?-1:0;
}*/
}
为什么我生成的对象没有全部被添加进去？而且ts,ts1,ts2,ts3,ts4每个Set里保存对象的数量都不一定。
