This post is a part 2 post of another one enquiry I made just days ago. Then with this code I will put last and through JButton1 I was able to attach a file and make it visible in a window north and east to the application. I am trying now to import a :
1) new image into a certain directory, for example into C:\output
2)a whole directory(folder) of images, lets say from C:\importImages
into C:\output .
For this I assume that I have some images in C:\importImages directory. Below , these are the 2 code samples that I need to fill in in order this thing that I want to work. This first method trying to load directories fails to run. I think that maybe its fault has to do something with Filechooser button from GUI Builder.
This is the whole method for loading a whole directory.
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:(for importing a whole directory(folder) from C:\importImages into C:\output ).
JFileChooser chooser = new JFileChooser();
chooser = new JFileChooser();
File f = chooser.getSelectedFile();
String filename = f.getAbsolutePath();
try {
ImageIcon ii=new ImageIcon(scaleImage(250, 250, ImageIO.read(new File(filename))));//get the image from file chooser (directories)
//jLabel1.setIcon(ii);
File srcDir = new File(filename);
File destDir = new File("C:/output/");
FileUtils.copyDirectoryToDirectory(srcDir, destDir);
}
catch (Exception ex) {
ex.printStackTrace();
}
}
and method for importing just a single file.
private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here(for importing a single image to directory C:\output ).

}
Thanks in advance!
The best way to learn something, try it yourself.
I can show you the possibilities. Try these ways useful to insert in your code.

Answer:
How to copy file in Java from one directory to another is common requirement, given that there is no direct method in File API for copying files from one location to another.
One way of copying file is reading from FileInputStream and writing same data to FileOutputStream to another directory.
Thankfully you don't need to reinvent wheel here, there are some open source library available which allows us to copy file in Java easily from one directory to another. One of such library is Apache commons IO which contains a class called FileUtils, which provides utility method for file related operation.
Copy and rename file on different location
FileUtils.copyFile(sourceFile, targetFile) can be used
String source = "C:/output/myImage.jpg";
//directory where file will be copied
String target ="C:/importImages/";
//name of source file
File sourceFile = new File(source);
String Filename = sourceFile.getName();
File targetFile = new File(target+Filename);
//copy file from one location to other
FileUtils.copyFile(sourceFile, targetFile);
