what does this line of code do? What is the value of x in here?

It's a static initializer block. See the JLS for the juicy details.
Basically, when the class is being loaded, this static block executes and initializes the static variable x to 5.

It does nothing useful. It declares a local variable "x" with an initial value, and then that variable goes immediately out of scope when the code reaches the } at the end of the block.
It doesn't change the real static variable "x" at all.
If it were up to me, I'd have the compiler issue a warning when it saw something like this.

Whoops! Ron is right... I overlooked the int declaration inside the block. My bad.
