Unable to rename and delete file in Java

Question

I am doing a project in Java using NetBeans and I need to modify a file. So I overwrite the whole file in another temporary file, but at the end I could not rename the temporary

Answer 1

I just tried 5 of the above project lines as below and got the desired result,

    File real =new File("F:\\nb\\project_inventory\\Employee_info.txt");
    real.delete();

    File tf = new File("F:\\nb\\project_inventory\\temp.tmp");
    try{
       tf.createNewFile(); // for creating the new file
       }
    catch(IOException e){
       e.printstacktrace();
       }
    File real =new File("F:\\nb\\project_inventory\\Employee_info.txt");
    tf.renameTo(real);

Employee_info.txt is getting deleted as well as temp.tmp is getting renamed as Employee_info.txt too.

Also, it is always recommended to put the code for delete/rename inside try/catch block like below:

 try{
        File real =new File("F:\\nb\\project_inventory\\Employee_info.txt");
        real.delete();
    }
    catch(IOException e){
        e.printstacktrace();
    }

Please provide the error message, to help you further.
