# does not come under the permissible identifier part. Check using Character.isJavaIdentifierPart('#') which will return false. For more information refer:

Why don't you try it out? It's very easy and you'll have the answer in less than a minute.

The compiler says:

C:\temp>javac Test.java
Test.java:3: illegal character: \35
