Compliance with the assured QoS assumes that all messages occurring in the physical communication system are already known, and taken into consideration, when design-ing the system. This also applies in particular to infrastructure protocols such as ICMPv6 and NDP.怎么理解

这句话的意思是，符合服务质量的合规性假定在设计系统时已经考虑到了物理通信系统中出现的所有消息，并且已经纳入了考虑。这尤其适用于基础设施协议，例如ICMPv6和NDP。换句话说，设计系统时必须考虑到可能发生的所有情况，以确保系统的性能符合预期，并且符合服务质量的标准。在设计系统时，必须考虑到可能影响服务质量的任何因素，包括网络拥塞、延迟、丢包等因素，并采取相应的措施来减少这些影响。

What kind of error messages can be expected from the 'Example.java' file if it is a non-project file and contains only syntax errors?

If 'Example.java' is a standalone Java file that is not part of any project structure, and it contains only syntax errors, you can expect to see compiler-generated error messages. These messages will typically indicate issues with the code's compliance with the Java language specification. Here are some common error messages you might encounter:

1. **SyntaxError**: This is the most basic error indicating a problem with the syntax, such as missing semicolons, unmatched brackets, or incorrect use of keywords.

   Example.java:1: error: ';' expected
       // Incorrect line here
   ^

2. **MissingTypeDeclaration**: If a class, interface, or variable declaration is incomplete, you'll get an error for this.

   Example.java:5: error: class, interface, or enum expected
     method(); // Missing 'class' keyword or '{'
   ^ 

3. **InvalidVariableName**: Names used in identifiers must follow certain rules (e.g., cannot start with numbers).

   Example.java:7: error: illegal name
       int$3 = 0; // Invalid because '$' is not allowed as a first character
   ^  

4. **UnresolvedReferences**: If you reference a class or method that hasn't been imported or defined, you'll get an error like this.

   Example.java:10: error: cannot find symbol
       MyClass myObject; // Error since MyClass is not declared
   ^

5. **RedefinedIdentifier**: If a variable, class, or import is accidentally redefined within the same scope, you'll receive an error.

   Example.java:15: error: already assigned to
       int x = 5; // First assignment
       x = 10; // Second assignment, generates error

To resolve these errors, carefully review the highlighted lines in the compiler output and fix the syntax issues according to the Java Language Specification. Make sure to adhere to proper indentation, curly braces, and correct usage of language constructs.
