Here is my insertion method for a doubly linked list. It works, but passing two parameters for the method seems cumbersome. Can anyone suggest a cleaner approach than this?
LinkedList list = new LinkedList();
Link link1 = new Link("A");
list.insert(list.head,link1);
Link link2 = n...
It's a challenge, in general, to debug someone's code problem remotely, especially when a question is vague or ambiguous. But sometimes I have a pretty good idea where the issue lies, and how to ferret out the problem, so I suggest debugging / problem solving steps. These are typically for questi...
I want to have distinct operations of numbers to get a number. For example
If number = 5
The result should show in System.out.println: 2+3, 6-1, 10-4-3-2-1, 1+6-4+5+2, the last one is important i want to have "+" and "-" operands with whatever combination wich equals a number, not only 5 but ver...
I am working on an interview question in which I need to find largest palindrome made from product of two 3-digit numbers. Here is the question. I came up with below example:

Oftentimes, I write small little dialogs or forms without a UI builder. I usually find myself having a lot of "container" panel variables that just float around. I found this leads to time-wasting experiences.
Where did I put that BorderLayout panel?
Oh right, here it is.
Wait, neve...

I'm working on a search utility that searches through source files. It's only the beginning of the project. It lacks a lot of features, but a backbone of the project works and it would be great if you can take a look at it.

My intention is to store user's last log in date and time when he logs in to the web page. I pass his username and password to the stored procedure to check whether is it correct or not! I believe it'll be fine to store his last login date and time if any record matches.

I am working my way through some exercises, using Java, to learn about programming. I have just finished the following Code Golf challenge:

This weekend, I ran into a peculiar problem of handling race conditions in Javascript.

I have a large word-file with over 240 000 words. I need to know if a specific word exists in this list quite fast. I thought that it would be a good idea to create a Radix Tree for this problem.

I just so happened to come across this and wanted to offer a non-SO point of view, as I believe this rightfully belongs on MSE as badges affect the entire Stack Exchange network.
I think this is a wonderful idea and have wondered myself why there isn't a silver and bronze level badge for this. ...

Let me start off by saying that I have several years of experience in Java, but now I need to learn Python, so I decided to make a calculator as it also is a community challenge.
