Java方法在运行后不打印任何内容

Question

我正在用Java制作一个小纸牌游戏。现在，我正在进行手工分类。但是，当我运行方法'handclassifier'时，我什么都得不到。以下是eclispe输出到控制台的示例：

标准输出

Your hand: 6 of Spades, Queen of Spades
Creek: 10 of Spades, 9 of Spades, Queen of Clubs 
Current value: 

正如您所看到的，即使满足了对的要求，handclassifier方法也不会返回任何内容。我让它在前两种方法之后运行，以便卡可以加载并按方法分类。比较代码中有什么问题吗？

Answer 1

while(stop = false) {

应该是

while(!stop) { 

或

while(stop == false) {

您要将false分配给stop变量，而不是将其当前值与false进行比较。
