我正在尝试编写一张3张牌扑克游戏并且已经遇到了＃34;表达式的类型必须是数组类型，但它解析为int＆＃34;我感到困惑的错误。这个错误似乎不像我做我的计数器的方式，但我在编码时很新，并且不明白错误在说什么。如果我不得不猜测我会说我的方法，但是当涉及到java时我很无能为力。下面有3个点，我收到错误。我已经包含了给我带来麻烦的部分以及它下面的整套代码。任何帮助表示赞赏。

以下是整套代码
class MyClass {
private boolean timeUp = false;
public void nextTuple() {
if (timeUp) {
EmitMyTuple();
ResetTimeCounterToZero();
timeUp = false;
} else {
boolean greater = CheckIfTimeIsGreaterThanOneSecond();
if (greater) {timeUp = true;}
}
}
SleepForFewMilliseconds();
}
答案 0 :(得分：0)
我认为这条线不会抛出这样的错误
for(int counter = 1; counter <3; counter++)
但这三个肯定会有问题
if (card1[counter - 1] == card2[counter])
...
if (card1[counter] > highcard) // error here
{
highcard = card1[counter]; // error here
因为你试图迭代card1和card2，它们是整数而不是数组
答案 1 :(得分：0)
在所有这三种情况中，card1和card2都不是数组。它们是直的int。订阅int没有意义（它甚至意味着什么？）。
