java delete file from folder -

i trying delete file: code , can't see wrong

system.out.println("users//"+"user"+i.getid());             file f=new file("users//"+"user"+i.getid());             system.out.println("can read: "+f.canread());             system.out.println("can write: "+f.canwrite());             system.out.println("can exec: "+f.canexecute());             system.out.println("exists: "+f.exists());             system.out.println(f.delete()); 

yes, have right read,write,exec , file exists. don't have exceptions

i have tried code , works:

public static void main(string[] args) {         try {             file file = new file("c:\\users\\akhil\\logfile11052015.log");             if (file.delete()) {                 system.out.println("success: " + file.getname() + " deleted!");             } else {                 system.out.println("failed: delete operation failed.");             }         } catch (exception e) {             e.printstacktrace();         }     } 

may can check if providing correct path in case , file exists there.

output: success: logfile11052015.log deleted!
