What does i mean in Java?

Answer 1

It's not specific to Java either. i can be a variable name in many different languages. For loop iterations i may stand for index.

Answer 2

Its just a variable name used in for loops its short for "iteration" but theres no diffrenece between using i or any other variable name you could use x instead if you wanted.

Answer 3

I is the name of the variable declared to be of int type, used for loops that I know of, for loops etc. It could easily be a different letter.
