public static double average(double[] x)
public static double min(double[] x)
public static double max(double[] x) As a beginner java programmer I still have problems in my code.. Could you help me to fetch the true answer.

Code:

Step 1... You need to make sure that your program can compile first. If you can't compile, you can't run. If you can't run, you can't test. If you can't test, you can't figure out what is wrong. If you can't figure out what is wrong, you can't fix.

So... Does the program compile? What issues are you having when you try to compile it?

That's a task list of errors in your program. You need to click each one. The IDE will take you to the error, with icons that explain the error. And you need to fix it.

Showing us the task list is pretty useless -- as we don't get any details about the error.


BTW, for a beginner, it is recommended to not use an IDE. An IDE takes care of tons of stuff, that a beginner needs to learn. I highly recommend that you use the standard javac compiler.

Look at lines 6 and 7 of your program:

What are 'b' and 'c'? You haven't declared variables named 'b' and 'c' anywhere, so the compiler doesn't know what you mean there.
