Title Body

I have created a program which searches for files in a source folder. If it finds any file, it processes that file and moves it to a destination folder, then looks for a new file in the source folder. It has to keep on checking the source folder for a file. I have used a thread to look for files in the source folder. The problem I am facing is whenever any exception is thrown during file processing, the thread gets stopped. I want the thread to be running even if an exception is thrown. It has to move the file that caused the error to some other folder and look for a new file in the source folder. How can I make the thread keep on running? Eg: public void run() { try { searchfile(); } catch(Exception e) { e.printStackTrace(); } } public void searchfile(){ ... } Update : I should be more clear in my question. Actually there are 4 source folders and 4 destination folders. I have to perform the same operation in each source & destination pair. So i have created 4 threads in one class and do the operation in separate class. class MainClass { public static void main(String[] args){ for(int i=0;i<4;i++){ SearchClass search = new SearchClass(); Thread thread = new Thread(search); thread.start(); } } } class SearchClass { public void run() { try { searchfile(); } catch(Exception e) { e.printStackTrace(); } } public void searchfile(){ ... } } All the thread wont stop running eventhough it caught any exception in middle. How can i do that?
