- 令牌上的语法错误“。”，@期望在此令牌之后 [英] - Syntax error on token ".", @ expected after this token

问题描述

几天前，我的Eclipse在Windows更新之前工作正常。现在我在Eclipse中尝试任何事情时都会收到错误消息。只是一个简单的程序，因为这将显示一堆错误消息：

  package lab6; 
 
 public class Hellomsg {
 System.out.println（Hello。）; 
 
} 
  

这些是我在同一行收到的错误，有我的

 System.out.println：
此行上的多个标记
 
  - 语法错误，插入）完成MethodDeclaration 
  - 令牌上的语法错误。，@这个标记之后的预期
  - 语法错误，插入标识符（完成MethodHeaderName
  

解决方案

你不能只是在类中间浮动语句在Java中，您需要将它们放在方法中：

  package lab6; 
 
 public class Hellomsg {
 public void myMethod（）{
 System.out.println（Hello。）; 
} 
} 
  pre> 
 
 
或 static 块：
  package lab6; 
 
 public class Hellomsg {
 static {
 System.out.println（Hello。）; 
} 
} 
  
 
My Eclipse worked fine a couple of days ago before a Windows update. Now I get error messages whenever I'm trying to do anything in Eclipse. Just a simple program as this will display a bunch of error messages:
package lab6;

public class Hellomsg {
    System.out.println("Hello.");

}
These are the errors I receive on the same line as I have my 
"System.out.println":
"Multiple markers at this line

- Syntax error, insert ")" to complete MethodDeclaration
- Syntax error on token ".", @ expected after this token
- Syntax error, insert "Identifier (" to complete MethodHeaderName"

解决方案
You can't just have statements floating in the middle of classes in Java. You either need to put them in methods:
package lab6;

public class Hellomsg {
    public void myMethod() {
         System.out.println("Hello.");
    }
}
Or in static blocks:
package lab6;

public class Hellomsg {
    static {
         System.out.println("Hello.");
    }
}
