Java better way to delete file if exists

Question

We need to call file.exists() before file.delete() before we can delete a file E.g.

 File file = ...;
 if (file.exists()){
     fil         


        

Answer 1

  File xx = new File("filename.txt");
    if (xx.exists()) {
       System.gc();//Added this part
       Thread.sleep(2000);////This part gives the Bufferedreaders and the InputStreams time to close Completely
       xx.delete();     
    }
