10 Tips to create Maintainable Java Applications

Hello all, if you are in software development then you know that creating an application is easy but creating a maintainable application that can pass the test of time in production is rather difficult and that's the main reason experienced Sofware developers are paid higher salaries compared to many other jobs. In this article, I am going to share with you some tips on creating maintainable Java applications which will help you not just in the new year, but also in all the coming years in your software development career.  One aspect of development, which is often overlooked by developers is to create applications that are both easy to maintain and support. Since software spends 90% of its lifetime in maintenance mode, it's very important that your application is easy to configure, support, and maintain. 

How to HashMap in Java? Example Tutorial

Hello friends, we are here today again on our journey to Java. I hope everyone is fine and ready to board our train of knowledge. Today we are gonna learn something very interesting and very exciting, yes I am talking about the HashMap class in Java which is the implementation of hash table data structure. In the past, I have shared my thoughts on How HashMap works in Java as well as frequently asked HashMap interview questions but I have never shared an example of how to use HashMap in Java, or when to use HashMap. Today's topic will definitely be very useful in coding and programming. This topic would surely decrease your time complexity if any task very significantly :p 

So what's the wait? Let's start!

How to Check/Uncheck CheckBoxes in a Page using jQuery? Example Tutorial

In the last couple of articles, I have shared a couple of useful jQuery tips like reloading web pages and working with tag selectors. Today, I'll show you how to check or uncheck a particular checkbox using jQuery, one of the most popular JavaScript frameworks. jQuery provides CSS like selectors which can make this kind of task trivial. If you remember, in HTML a checkbox is checked if the "checked" attribute is present and its value is not false, otherwise, it's unchecked. By using jQuery function prop() you can dynamically add this attribute or if present we can change its value i.e. checked=true to make the checkbox checked and checked=false to mark the checkbox unchecked.

Difference between Stable and Unstable Sorting Algorithm - MergeSort vs QuickSort

Recently in one interview, after some initial questions about sorting algorithms e.g. how do you write QuickSort or the difference between QuickSort and MergeSort, the interviewer asked about do you understand the difference between stable and unstable sorting algorithms? This question was new to my reader, so he says, Sorry, never heard about that. The story ended there, and Interviewer moved on to the next question but like many of us, my reader went on to find more unanswered questions and ultimately he asks me what is the meaning of a stable and unstable sorting algorithm? Some of you might be heard about it and many of you might not know about this distinction, I'll try to answer this question in this article.

How to solve java.lang.classnotfoundexception sun.jdbc.odbc.jdbcodbcdriver in Java 8

java.lang.classnotfoundexception sun.jdbc.odbc.jdbcodbcdriver exception comes in Java 8 because it has removed the JDBC ODBC bridge driver class "sun.jdbc.odbc.jdbcodbcdriver" from JDK and JRE. This class is required to connect any database using Object database connectivity driver e.g. Microsoft Access, but unfortunately, you cannot use it from JDK 8 onward. In order to solve this error, just use the Jackcess library or a commercial driver like HXTT. Normally, in pre-Java 8 world, java.lang.classnotfoundexception sun.jdbc.odbc.jdbcodbcdriver error comes when you try to connect to the Microsoft Access database from Java using JDBC and JDBC ODBC bridge driver is not available in the classpath.

Does Standard Column Width of 80 On Coding Make Sense in Modern Era of Big Monitors?

One of the oldest coding practices is to keep line width 80, and many of us follow it blindly but have you ever thought about why we have this practice in the first place? I believe it was to make your code more readable in the age of small monitors so that the whole content can fit on the screen, or it might have originated from the age of punch cards, which was used to be 80 columns wide. This sounds reasonable when we think about those old days but do you think this rule makes sense now? We are now living in the age where most of the developers have got large monitors, which can show up to 180 characters, doesn't this is wastage of precious monitor space? It also makes your code unnecessary long, than it actually is.
