Java delete a folder and subfolders recursively

Java source code for deleting a folder and subfolders recursively.
Code for copying and moving files is here.
Working source code example:

public final class FileIOUtility {
    private FileIOUtility() {}
    public static boolean deleteFile(File fileToDelete) {
        if (fileToDelete == null || !fileToDelete.exists()) {
            return true;
        } else {

Java: Loading images in JFrame - Reusable ImageFrame

Sometimes we need to show multiple images in separate window by using single line statement :

new ImageFrame(inImg, "Input Image ");// inImg is reference to Image object

The code below can be used to load images in JFrame as a separate window.

Tutorial on Ibatis-Using Eclipse Ibator plugin to generate Persistence POJO Models, SqlMap and DAO :: with coverage of Dynamic SQL and working downloadable example

IBatis is a lightweight persistence framework that maps objects to SQL statements. The SQL is decoupled from the application logic by storing in XML descriptor file . SQL mapping is done by data mapper to persist objects to a relational database. 
In this article i am going to discuss on how to use ibator plugin in eclipse to generate Java model objects from your database, the DAO interface and its auto implementation to access your db and auto generated SQL map xml files. And also we will deal with fun of dynamic SQL.  The Link for downloading the working eclipse project is given at the end of article. For more detail about ibatis visit the references at last of this article.


Part A: Ibator/DB Configuration

Step 1. Installing IBator

Visit this link and download ibator plugin for eclipse
