type-casting

Hello.

well.. I use red5 and setting/getting attributes using the IConnection class but tha's really not relevant.

'L' means long in java. so 0L is 0 type Long instead of just '0' which is 0 type Integer.

the following error message:

stack trace: java.lang.ClassCastException: [Ljava.lang.Long; cannot be cast to java.lang.Long

what's the difference between [Ljava.lang.Long and java.lang.Long ?

thanks!

For those who don't, PHP.net says: PHP does not require (or support) explicit type definition in variable declaration; a variable's type is determined by the context in which the variable is used. Love it or hate it, PHP re-casts variables on-the-fly… >>> More
