Deleting directory contents

Question

Hi All.
I have an application which read the contents of a directory and deletes the files in them. If the directory has subdirectories, i need to enter the subdirectory and delete the files in there too. however, I do not want to delete the directory itself after it has been emptied.
I have tried calling a recursive delete method but I can't get it to work completely. It deletes most of the files but it does not delete some of them as it looks for them in the wrong directory. I have posted the method below.
any help will be appreciated. Thanks.
public void emptyContents(String cmf_dir_path){
System.out.println("entering "+cmf_dir_path);
File cmf_dir = new File(cmf_dir_path);
File[] cmf_contents = cmf_dir.listFiles();
for(int i=0;i<cmf_contents.length;i++){
boolean delval = false;
File the_file = (File)cmf_contents;
if(!the_file.getName().endsWith(".log")&&
the_file.exists()){
delval = the_file.delete();
if(delval){
System.out.println("this file was deleted");
if((!delval) &&(!the_file.getName().endsWith
(".log"))){
if(the_file.isDirectory()){
emptyContents(the_file.getAbsolutePath());
else{
System.out.println("could not delete this
file");

Hi,
I have modified your method to suit your requirements.. i.e. It deletes all the files except the .log files from the directory and also from its subdirectories.. but it will not delete the directories..
Hope this helps..
look like this [ i ] is for Italic.. So I gave a space in between.. check for that..
This is the modified method..
public void emptyContents(String cmf_dir_path){
System.out.println("entering "+cmf_dir_path);
File cmf_dir = new File(cmf_dir_path);
File[] cmf_contents = cmf_dir.listFiles();
for(int i=0;i<cmf_contents.length;i++){
// boolean delval = false;
// File the_file = (File)cmf_contents;
if(!cmf_contents[ i ].getName().endsWith(".log")&&cmf_contents[ i ].exists()){
if(cmf_contents[ i ].isDirectory()){
System.out.println( cmf_contents[ i ].getName() +" is Directory");
emptyContents(cmf_contents[ i ].getAbsolutePath());
else{
boolean delval = cmf_contents[ i ].delete();
System.out.println( cmf_contents[ i ].getName() +" is File");
if(delval){
System.out.println("this file was deleted");
} // end of if not .log file
else {
System.out.println( cmf_contents[ i ].getName()+" is a log File");
}//end of for.
} // end of emptyContents()
