我有一个错误，我无法理解 [英] I have an error that I can't understand it

问题描述

private static void menu（）{

（错误出现在私有静态void菜单中，我标有红色）



错误：非法开始表达

  public   static   void  main（ String  [] args）{
  //  这里的TODO代码应用程序逻辑 
 
 students.put（（（ long ） 101010 ）， new  HomeStudent（  Pisty，  Bolt，   Oradea，  0 7568478685，  [e-mail]， new  Date（）， -   2000 ，Course.Computing， 101010  ））;

我尝试过：



我尝试了在互联网上找到的所有来源，似乎我无法得到它

解决方案

查看错误消息，并且在它正在抱怨的函数之前的代码 - 通常编译器报告问题的行是在实际错误之后，因为那是在可检测到问题的时候。与书籍中只找不到页面的方式大致相同，因为在缺失页面之前开始的句子不会在下一页上结束！

您应该尝试添加一个'}'那里

 menu（）; 
 }   //  尝试添加此行 
  private   static   void  menu（）{ 

请参阅跟踪：学习Java语言（The Java™Tutorials） [ ^ ]。

private static void menu () {
(the error is here at the private static void menu I have it marked with red )

Error: illegal start of expression

menu () ;

What I have tried:

I tried all of the sources that I could find on the internet it seems that I cannot get it

解决方案

Look at the error message, and at the code immediately before the function it is complaining about - very often the line that the compiler reports a problem with is after the actual error because that's when the problem is detectable. Much the same way that you only find a page is missing from a book because a sentence that starts before the missing page doesn't end on the next one!

You should try to add a '}' there

menu () ;
} // try to add this line
private static void menu () {
