How to delete a folder with files using Java

Question

I want to create and delete a directory using Java, but it isn\'t working.

File index = new File(\"/home/Work/Indexer1\");
if (!index.exists()) {
    index.m         


        

Answer 1

In this

index.delete();

            if (!index.exists())
               {
                   index.mkdir();
               }

you are calling

 if (!index.exists())
                   {
                       index.mkdir();
                   }

after

index.delete();

This means that you are creating the file again after deleting File.delete() returns a boolean value.So if you want to check then do System.out.println(index.delete()); if you get true then this means that file is deleted

File index = new File("/home/Work/Indexer1");
    if (!index.exists())
       {
             index.mkdir();
       }
    else{
            System.out.println(index.delete());//If you get true then file is deleted




            if (!index.exists())
               {
                   index.mkdir();// here you are creating again after deleting the file
               }




        }

from the comments given below,the updated answer is like this

File f=new File("full_path");//full path like c:/home/ri
    if(f.exists())
    {
        f.delete();
    }
    else
    {
        try {
            //f.createNewFile();//this will create a file
            f.mkdir();//this create a folder
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
