Java Sorting: Comparator vs Comparable Tutorial
2008-07-10 08:11:00 Java Comparators and Comparables? What are they? How do we use them? This is a question we received from one of our readers. This article will discuss the java.lang.Comparator and java.lang.Comparable in details with a set of sample codes for further clarifications.PrerequisitesBasic Java knowledgeSystem RequirementsJDK installedWhat are Java Comparators and Comparables?As both names suggest (and you may have guessed), these are used for comparing objects in Java. Using these concepts; Java objects can be sorted according to a predefined order.Two of these concepts can be explained as follows.ComparableA comparable object is capable of comparing itself with another object. The class itself must implements the java.lang.Comparable interface in order to be able to compare its instances.ComparatorA comparator object is capable of comparing two different objects. The class is not comparing its instances, but some other class?s instances. This comparator class must implement the java.lan... More About: Tutorial , Java , Tech , Sorting
Create/Restore Internet Explorer desktop shortcut
2008-06-24 14:05:00 Internet Explorer (IE) shortcut on Windows desktop is missing! May be it was deleted accidentally or missing due to some unexpected reason. So what would be the way to recreate it? You can create a shortcut just by right clicking on Windows Desktop . But you must give the application path to Internet Explorer installation. How would you find it?You would do a search on Windows for iexplore.exe on your C drive (Windows drive); and you'll end up seeing a number of iexplore.exe files on your machine. Are these the ones you have to use? which one out of these? Not exactly. The expected executable will not be shown by a Windows search. The correct file is a "protected operating system file", also it's hidden. By default Windows Explorer hides those files, but still you can view such files by changing the folder options as shown in the image.

Change Apache Tomcat port 8080 to 80 or another port number

Six sixes in one over in Twenty20 Cricket - World record
2007-09-20 14:57:00 Six sixes in one over in Twenty20 (Twenty Twenty, T20) Cricket ? Oh! World record!!! It was an amazing over; all the balls went over the rope like rockets. The Start was Yuvraj Singh from India, and the poor bowler was Stuart Broad (England). This happened on 2007-09-19, in Twenty20 world up match. Yuvraj did this in the 19th over. Unsurprisingly, he scored 50 runs in 12 deliveries, creating another world record. And think for a minute? He scored 50 with 3x4 and 6x6, which adds upto 48 runs in 9 balls. This world record will not be broken for a longer time and will stay than any other record?With this six sixes, Yuvraj joined the club of Six Sixers as the 4th person. Before him; West Indies great Sir Garfield Sobers and India's Ravi Shastri joined there while Herschelle Gibbs joined this club this year in March. Well done Yuvraj.

[Java Tips] Add Array into a List and convert a List into an Array
2007-09-20 14:31:00 With Java , putting contents of an Array into a new List object or adding into an existing List object can be achieved easily using a for() loop; just by going through each and every element in array and adding to List one at a time. But that is not needed. Java has provided a method to achieve that easily; just with one method call.
