Talk:How to swap variable values in Java ME using bitwise operations

From Nokia Developer Wiki

i do seriously doubt that this code is any faster than swapping using a temporary variable... i think that variable assignement is at least as fast as a binary operation, if not faster. your version is making 3 binary xor, a version using temp variable will be using 3 assignement and so the 2 will execute as fast.

Ya it's right but this concept is useful for memory utilization. because the third variable increases the memory size little bit.--vkmunjpara 10:18, 19 September 2009 (UTC)

Level: basic

This is a simple code but it uses a Bitwise XOR operator for swapping the values between two variables. So the extra third variable is not needed for swapping the values between variables.
