What is the difference between += and =+?

Question

What is the difference between += and =+? Specifically, in java, but in general also.

Answer 1

The += operation as you said, is used for increment by a specific value stated in the R value.Like,

i = i+1;
//is equivalent to 
i += 1;

Whereas, =+ is not any proper operation, its basically 2 different operators equal and unary plus operators written with each other.Infact the + sign after = makes no sense, so try not to use it.It will only result in a hocum.

i =+ 1;
//is equivalent to
i = +(1);
