Append and Renaming of File

[abhinav01]

Hi,

I have a folder where i have image files having names in format 001A0110.676

My requirement is to rename these files. I have to remove . and append IW to the start of all filenames. So my filename should be like IW001A0110676

Please suggest how to implement this through java.

Thanks
Abhinav

Java 6 or 7 ? :P

There is a class named File with the method renameTo!
The only thing you have to do are string operations! Do you have problems here?

Thanks for reply. I am first trying to append IW to names. I have written below code can you tell me where i am getting it wrong?

public static void main(String args[])
{

try {





// inputpath = args[0];
// outputpath = args[1];

inputpath = "C:\\Isuzu_CS_Test";
outputpath = "C:\\Isuzu_CS_Test_out";



File f = new File(inputpath);


String[] catname = f.list();


System.out.println("Total Files Available To Rename = "+catname.length);
File[] listOfFiles = f.listFiles();
for (int j = 0; j < listOfFiles.length; j++) {
if (listOfFiles[j].isFile()) {
String text = listOfFiles[j].getName();
System.out.println(text);
File F5=listOfFiles[j];
System.out.println("F5 ="+F5);
String text2="IW"+text;
File F6= new File(text2);

System.out.println(F6);

F5.renameTo(F6)

}}




}catch (Exception e){
System.out.println("Exception in Main :: "+e);
System.exit(1);
}

}
}
