What is the difference between += and =+?

Question

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

Answer 1

+= is a way to increment numbers or String in java. E.g.

int i = 17;
i += 10;  // i becomes 27 now.

There is no =+ operator. But if you do i =+ 10; it means i is equal to +10 which is equal to just 10.
