Question

++d means stands for in java​

Answer 1

Answer:

++ and -- operator as prefix and postfix

If you use the ++ operator as prefix like: ++var. The value of var is incremented by 1 then, it returns the value.

If you use the ++ operator as postfix like: var++. The original value of var is returned first then, var is incremented by 1.

The -- operator works in a similar way like the ++ operator except it decreases the value by 1.
