Wow!. You seems to be great at asm. I like to learn that too. I know a bit. But I like to go further. There is no end to it!

Thank you for the explanation. I used to practice reverse engineering of software when I was home after A/Levels. I just had a memory of it.

Oh. It's good. :D I just wrote an explanation of the mistake. Glad that you have found the error. Anyway, I will attach my answer too. Just in case you like to have a look. :) for(x=1;x<5;x++); See that semi colon after then for loop declaration. That tells the compiler that the line has ended. Thus...

I have seen programs Pushing parameters in to the stack before calling a function. (While disassembling little executable files.) . I am taking about x86 assembly.

There is no much about me still. I am 24. Still studying for bachelors. And following another degree course towards an IT degree(currently postponed a bit). At the university, I am following a degree course with Chemistry, Mathematics and Statistics as subjects. And I like IT more than those applied...

Yes. Switch block is the best way to handle this kind of work.
And some exceptions should also be handled. I didn't bother mentioning. He might not know about exceptions yet.

import java.util.Scanner; /** made by gayan bandara. date 07.08.2010 to make a calc*/ public class Gayan_calculator{ static void list(){ System.out.println("1.Add numbers"); System.out.println("2.Substract numbers"); System.out.println("3.Multily numbers"); System.out.println("4.Divide numbers"); }...

Well, when you use "if" there should be a condition to check. The code inside the "if" block will only be evaluated only if the condition of the "if" block is true. I think you are aware of it. Let's see your "if" block. if(selection==+||selection==-||selection==*||selection==\) selection==+ This is...

with input.nextInt(), the scanner is waiting for a integer value. But you enter an character (char ) . It is the cause for the inputMismatchException. There is no method for reading next character value. But there is a method named "next()". I think you will be able to use that and some casting ( co...

Half means?.
Normally, the argument list is a parameter of the main method.
So,
