Order of execution of parameters guarantees in Java?

Questions:

Given the following function call in C:

fooFunc( barFunc(), bazFunc() );

The order of execution of barFunc and BazFunc is not specified, so barFunc() may be called before bazFunc() or bazFunc() before barFunc() in C.

Does Java specify an order of execution of function argument expressions or like C is that unspecified?

Answers:

From the Java Language Specification (on Expressions):

15.7.4 Argument Lists are Evaluated Left-to-Right

In a method or constructor invocation
or class instance creation expression,
argument expressions may appear within
the parentheses, separated by commas.
Each argument expression appears to be
fully evaluated before any part of any
argument expression to its right.
