Incrementing and decrementing.

[James Elsey]

Am I understanding this correctly...?

int myInt = 1;
System.out.print("My int is :" + myInt++);

will print "My int is : 1
The reason for this is because the compiler acts like this : use the variable, then increment it after

int myInt = 1;
System.out.print("My int is :" + ++myInt);

will print "My int is : 2
The reason for this is the compiler acts like this : increment the variable BEFORE using it


The compiler therefore must be smart enough to understand the scope of the variable, so it knows when it can increment it?

I'm just trying to understand these operators correctly

Thanks

Your understanding is correct. The Java Language Spec includes some detailed and highly technical language about precisely when the increment/decrement can happen in either case, but it boils down to just what you've said here.
