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:
几天前，在 Windows 更新之前，我的 Eclipse 运行良好。现在，每当我尝试在 Eclipse 中执行任何操作时，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.");
}
These are the errors I receive on the same line as I have my
这些是我在同一行收到的错误
"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"

You can't just have statements floating in the middle of classes in Java. You either need to put them in methods:
在 Java 中，不能只在类的中间浮动语句。您要么需要将它们放在方法中：
package lab6;
public class Hellomsg {
public void myMethod() {
System.out.println("Hello.");
}
}
Or in staticblocks:
或者在static块中：
package lab6;
public class Hellomsg {
static {
System.out.println("Hello.");
}
}

You can't have statements outside of initializer blocks or methods.
您不能在初始化程序块或方法之外使用语句。
Try something like this:
尝试这样的事情：
public class Hellomsg {
{
System.out.println("Hello.");
}
}
or this
或这个
public class Hellomsg {
public void printMessage(){
System.out.println("Hello.");
}
}
回答by Jens
You have a method call outside of a method which is not possible.
您在方法之外有一个方法调用，这是不可能的。
Correct code Looks like:
正确的代码看起来像：
public class Hellomsg {
public static void main(String[] args) {
System.out.println("Hello.");
}
}
