Java 在另一个文件中找不到类

我查看了其他用户提出的类似问题的答案，但仍然不明白为什么我无法找到我创建的两个类的符号错误

我的头发看起来像这样

StacksAndQueuesProblems/threestacks

在

threestacks

目录中，我有以下

.java

文件：

FullStackException.java
fixedMultiStack.java

从

StacksAndQueuesProblems

目录中，我试图执行

javacThreeStacks/*.java

但是，我得到以下错误：

    threestacks/fixedMultiStack.java:20: error: cannot find symbol
            throw FullStackException("ERR: That stack is full!");
                  ^

FullStackException.java

package threestacks;

public class FullStackException extends Exception {

    public FullStackException(String message) {
        super(message);

fixedMultiStack.java

package threestacks;

    private int numberOfStacks = 3;
    private int stackCapacity;
    private int[] values;
    private int[] sizes;

    public fixedMultiStack(int stackCapacity) {
        this.stackCapacity = stackCapacity;
        values = new int[stackCapacity * numberOfStacks]; // Holds all 3 stacks
        sizes = new int[numberOfStacks+1]; // Holds the number of items in each stack
    }

    /* push value onto stack */
    public void push(int stackNum, int value) throws FullStackException {

        int topIndex = indexOfTop(stackNum);
        int value = values[topIndex]; //Get top

文件fixedMultiStack.java中存在编译错误。应该是

throw new FullStackException("ERR: That stack is full!");

这不应该是

抛出新的SomethingException（“somestring”）？你似乎忘记了新的

。投票结束更像是一个印刷错误。谢谢你的回答，但这值得投反对票吗？是的，进一步考虑，你是对的，没有。否决票被删除。但是，错误消息会准确地告诉您问题所在，因此在将来，您需要更仔细地校对相关行，以避免类似的粗心错误。祝你好运
