public static void main(String[] args) {

for (int i = 0; infantryNum <= 10 || artlleryNum <= 10 || tankNum <= 10; i++) {
double randomNo = Math.random();
if (randomNo < 0.3) {
soldiers.add(new Infantry());
infantryNum++;
} else if (randomNo < 0.6) {
soldiers.add(new Artillery());
artlleryNum++;
} else {
soldiers.add(new Tank());
tankNum++;
}
}

Officer officer = new Officer();
officer.setSoldiers(soldiers);
officer.attack();
officer.order();
}
}

这位大哥代码是真滴强
