我的刽子手程序有问题。当我运行它时,当你猜错字母时,包含 int 变量“lives”的标签应该会更新。但由于某种原因,它不是。我把它作为测试机制放在我的代码中,它甚至没有出现在这里。
if (used[letter] = false) {
System.out.println("test");
然而,当我把它放在这里..它确实有效..
if (finished == false) {
boolean found = false;
boolean www = false;
System.out.println("test");
if (used[letter] = false) {
它几乎让我相信 used[letter] 默认情况下是正确的,而实际上不应该如此。变量在最顶部声明。有什么想法吗?
