How to wait on file creation in Java

-
Here are some steps that we can remember while move in to coding part
  1. Iterate the (!file.exist()) blog till this block becomes as a false . so for that we can use Thread class and do Thread.sleep(10). that will wait for 10ns  and once time has been expire again it start same loop . means every 10 ns it will check on directory whether file is exist or not . if not then iterate.
  2.  once it got the file on directory then while loop iteration will stop and terminate the execution of while block

            try {
                Thread.sleep(10);//wait for 10 ns
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        System.out.println("Finally got the =>"+statText.getName());

    }

    public static void main(String[] args) {
        FileOperation write = new FileOperation();
        write.ProcessFile();
    }
}

Java Design pattern

-
 Singleton Design pattern :-  it's Creational Design Pattern as we need to have only one instance of our class for Ex:- Logger,DBConnector. SingleObject class have its constructor as private and have a static instance of itself. Code:-  public class Singleton { private static Singleton object; private Singleton() { } public static synchronized Singleton getInstance() { if (object == null) object = new Singleton(); return object; } } Eager Initialization :-  public class Singleton { private static Singleton object = new Singleton(); private Singleton() { } public static Singleton getInstance() { return object; } } Double checked Locking :-  public class Singleton { private static volatile Singleton obj = null; private Singleton() { } public static Singleton getInstance() { if (obj == null) { synchronized (Singleton.class) { if (obj == null) obj = new Singleton(); } } ...
