I am here seeking knowledge of people who actually know what they are talking about.
In mobile development, specifically Andriod, is there any reason to use
variable1 = variable1 + variable2 over
variable1 += variable2 ?
This was a subject that came up recently and my lecturer simply said not to use += as it is slower and takes more processing power than the other method.
I have googled, but I am unable to find any information either way confirming or denying this, and when asked, the lecturer can provide no reasoning other than 'it just is'.
Based on other inaccuracies he is teaching, I am wondering if there is any truth is this.
Any help appreciated.
