24 - Incrementing and Decrementing Variables in Java Code

In this lesson, we learn how to increment and decrement variables in Java code. This is useful when constructing loops of any kind, and also for performing many calculations in code.

first time in all these years i really understood post increment and pre increment operators. Thankyou really

b = a++
you can just assume it's: "b = a"++
b = a because the incrementation doesn't interfere with the assignment of the value of b

Then when it is:
b = ++a (here the incrementation interferes with the assignment of b so we have to take it as a whole)
You can't do: "b = ++"a
so you have to include

"b = ++a" and treat [++a] as one thing, lets call it [Incremented a].
"[b] = [++a]" >>> [b] = [incremented a]

This is how I reasoned it in my brain.

This one is super helpful! Really appreciate it

Can you increment and decrement in the same class ? I'm trying but it is printing out the increment for both when I call the variable.

Hope I'm explaining this right.
