What is the difference between += and =+?

Question

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

Answer 1

When you have a+=b, that means you're adding b to whatever's already in a. If you're doing a=+b, however, you're assigning +b to a.

int a=2;
int b=5;
a+=b;
System.out.println(a); //Prints 7

a=2;
b=5;
a=+b;
System.out.println(a); //Prints 5
