/*im having an error in my code whenver i try to compile it. i cant find the error in my code..

im a strter in java proggraming language..

Hi first I'll explain the first 3 lines.

public static InputStreamReader Reader = new InputStreamReader (System.in);
public static BufferedReader input = new BufferedReader(reader);

The first two lines are simply for getting a user's input that's all. Just creating objects that gets the user's input.
Actually in the second line of these 3 line is where the error is appearing, it is in the argument reader which should be Reader, because reader is not defined anywhere and bear in mind that Java is a case-sensitive language which means that reader is not the same with Reader.

The thing is the input which is an object of the BufferedReader class takes an object of the InputStreamReader class as an argument, in our case Reader. But I believe that it's more confusing than explanatory, so if you are beginner take them as they are, or try to google those classes to see their features.

you can do those two lines in one like this:

BufferedReader input = new BufferedReader(new InputStreamReader (System.in));

use them any way you want.

As for the last one of the three lines, it's the main function, and you'll use it many many times, learn it as it is.


But I do have remarks on the code's logic. I guess you want to find average but Ave is an integer, and the formula by which you calculate the average is a bit strange.

try checking your codes. i can see error on your codes. java is very case sensitive. 1 wrong character and your program will not work.

and there's something wrong in calculating your Average like Penny said

try running it and look what the errors said
