To set a breakpoint at the end of an arbitrary block is not possible (without byte-code hacking).

If it is a method body, then it is possible: you can set a Method breakpoint. Do this by double-clicking on the method definition line:

(notice the little arrow?) and then in the breakpoints view, select the breakpoint to see both an Entry and an Exit option tick-box in the displayed properties:

The little arrow indicates that, by default, we have set a breakpoint on entry to the method.

Now select Exit (and deselect Entry) and you will see this in the breakpoints view:

(There is a different little arrow, indicating an exit breakpoint.)

Now run the debugger on this little breaker ('Debug As a Java Application') and it will stop on the exit brace of the method:

and the local variables (only a in this case) are now visible (with the correct values) in the Variables view:

It is worth noticing that this type of breakpoint traps method exit however this happens -- even, for example, if we exit by throwing an exception.
