java - 二十一点 split 时爆牌

Question

在我的二十一点中，我让玩家击牌或站立，然后测试结束循环，您有以下代码:

int runLoopCount1 = 0;
    for (int i = 0; i < players.length; i++) {
        if (players[i].wantSplit = false){
                if(players[i].getStatus() == true){
                    runLoopCount1++;
                }
        }

        else if (players[i].wantSplit = true){
            if ((players[i].splits[0].busted == true||
                 players[i].splits[0].standed == true) &&
                (players[i].splits[1].busted== true ||
                 players[i].splits[1].standed == true)){ // null pointer here 
                        runLoopCount1++;
                }
            }
        }
                
   if(runLoopCount1 == players.length){
        runLoop = false;
   }

现在我得到一个NullPointerException。我不知道为什么？

你的意思是if(players[i].wantSplit = false)还是if(players[i].wantSplit == false)与 if(players[i].wantSplit = true) 或 if(players[i].wantSplit == true)
