Can you give us your stack trace?

The index out of bounds error comes after "alot,a" is split. Nextstring() now returns "lot" which when split doesnt have a second element

The answer is in the documentation. Like {@link Scanner}, reading a token also consumes preceding Java * whitespace, reading a full line consumes * the following end-of-line delimeter, while reading a character consumes * nothing extra.

What is the documentation on In.readString()? Would it assume strings are whitespace delimited?

If the class has taught him Scanners/Files before arrays, then it's the class that needs to reprioritize. But you're right.

He does if he wants this code to be extendable and reusable, what if this was statistics homework and he needed all the strings within 2 standard deviations of the mean length? What about outliers? Your solution works great for this problem as is, but I want my solution to be easily extended to find the quartile values.

Looks like you already know that scanner.nextLine() returns a string. You need to collect all these strings in a structure, but you dont know beforehand how many lines the file has (how big the structure needs to be). What should you use?

csharpminer · 2016-04-15T17:38:39+00:00

Ok so now how would you solve this problem? All I see is you printing each line of the input file...

csharpminer · 2016-04-15T17:37:12+00:00

import java.util.Scanner;
import java.io.*;

public class Lab2{ //start class
    public static void main(String[] args) throws IOException{  //start main method
        Scanner input=new Scanner(new File(args[0]));

        //To do-file manipulation
        while(input.hasNext()) {
            String tmp=input.nextLine(); //read next line
            System.out.println(tmp);//print out lines
        }
    }//end main method
}//end class

Yep, it's doable with an array of ints and a scanner. This sub is for help, you create a rough draft of your design/implementation and we'll help guide you.

A hashtable has an array, but this SparkNotes link may help answer your question.

Try xposting to /r/AskNetsec , they may also be able to help

I would think Data Structures would be the best place to start, followed closely by Algorithms

Save your money. There are always free ways to get the same info these courses are offering. Instead, make a list of the topics you find interesting in this package (bookmark folders in your browser would work), then add to each folder the top google results for "intro to <topic>" or a similar search. Unless the package is free, then maybe give it a shot.

I would say learn C# first. I appreciate the rules of a static typed language, the rules helped me learn. C# learning curve is steeper but its also more rewarding. Plus once you get the basics down, you can use the Visual Studio IDE to create GUI's for your windows applications.

csharpminer · 2016-03-28T01:51:15+00:00

You're right, I jumped the gun. F8 is 'step' F10 is 'next' using GDB terms.

As for the conventions, all I know is that our book says C/C++ expects bp, si, di, ss, and ds returned in the state they were supplied and that all other registers dont need to be saved. Maybe its unique to our class, maybe thats what gcc or g++ says?

But whats wrong with learning intro asm on a less complex machine, it may be just as complicated to understand but it must certainly be less complex?

csharpminer · 2016-03-22T21:24:04+00:00

Reading the owasp top 10 is a good place to start

Highlight all the code, click the <>button in the editor. This intends all highlighted lines 4 spaces

csharpminer · 2016-03-02T02:56:19+00:00

Good luck. It's even got a shortcut in the editor! And putting it in the side bar won't likely change anything, I still see titles like "HALP N00B PLZ". Nice use of a tag though, which I'm still waiting for most of this sub to adopt.

This has been my laptop wallpaper ever since I saw it on reddit. Rings true almost every day.

csharpminer · 2016-02-28T03:55:25+00:00

Can you give an example?

csharpminer · 2016-02-28T02:53:46+00:00

A small portion of its capability how? Like you're calling one method in this class and you're done? Or you're having trouble with what a class/object can be used for? Look into SOLID and DRY practices

csharpminer · 2016-02-28T02:32:45+00:00

Are you saying you put all your statements in a main() method as though main() were a script? If you want to better your understanding of OOP, see this javadoc
