无法将游戏重置为上一轮JAVA

Question

我制作了一个程序，要求用户提供他们的宠物名称，并将其状态分配给5轮。如果宠物太生气了就放下了。

我遇到的麻烦是允许用户在宠物死亡前重新开始游戏的早期阶段。

编译代码有助于说明问题。

任何帮助都将不胜感激。

首先，您应该在提交问题之前查看代码中的编译错误。 请阅读评论中提供的链接，了解如何提交正确的问题。

我尝试编译您的代码，但它有以下错误：

java2.java:51: error: '.class' expected
                    emotionalstate = wheretogo(emotionalstate[]);
                                                               ^
java2.java:75: error: '(' or '[' expected
        Scanner scanner = new scanner;

这意味着在第51行，你正在传递emotionalstate[]，这是情绪状态数组，而emotionstate本身就是一个数组，所以你要传递一个数组的数组。

所以只需将其更改为emotionalstate = wheretogo(emotionalstate)

即可

在第75行中，Scanner对象的初始化错误，将其更改为Scanner scanner = new Scanner();
