Inter Thread Communication(Producer-Consumer Problem) simplified

Inter thread communication is very interesting topic where you learn how two thread can talk to each other in a multi-threaded environment. And this is demonstrated with a very simple example of Producer-Consumer problem. Object class's wait and notify method will be used for inter thread communication.
I'm assuming two thread
  1. Producer
  2. Consumer

These will be spawned using main thread.

  • Producer will try producing Product. Produce action will be represented by making Available property in Product Object true. 
  • And consumer will be consuming that object by making available property false. 
  • Same object will be used to pass to both threads for inter thread communication
  • Code accessing same object will be synchronised 


Main methods used are :
Thread.sleep >> It will be used to give some delay so that we can understand code execution.
Object.wait >> Wait will be called on product which will make current thread to release lock and wait.
Object.notify >> Notify will be called on product object. This will make notify waiting thread and will allow to execute as soon as current thread goes to wait.
If you are not able to see code please access from here.


Output :
Product Consumed.
Product Produced.
Product Consumed.
Product Produced.
Product Consumed.
Product Produced.
Product Consumed.
Product Produced.
Product Consumed.

How to do AJAX using XMLHttpRequest for large data

Your are at right place if you are : working on loading huge amount of data from server be it JSON or XML document getting truncated JSON Response string  observing $.ajax call failure due to JSON.parse is compiling about invalid char while parsing JSON  observing performance lag while parsing JSON using $.ajax observing response code 200 but there is not response received in $.ajax success call  Uncaught InternalError: allocation size overflow in $.ajax If you are loading large data from server then you need to consider lot of factors impacting load time. There can be optimization on server as well as client. Coming to client, most commonly used API for AJAX is JQuery.ajax. But when it comes to fetching large data set from server be it in JSON format or XML document, you might end up facing issue mentioned at the beginning of this blog. I observed that in case of large JSON String in response, response string is being truncated. Also, if string is not truncated, JSON.par...

Caching mechanisms in modern world browser

Image
           Getting data locally is always faster than the getting data from server. There are different types of caching mechanism that can be used to cache data on browser for optimizing performance and faster data retrieval. We will see some of the data store that can be used on client to cache or store data. 1. Session Storages     This is a very well-known storage on browser. Commonly uses to session specific data on this store. We can infer a current tab as one session. Session storage will not be available across tabs or new tab. Maximum limit of of session storage is 5MB.     Limitations:     It cannot use to persist information across tab or sessions     It cannot store data more than 5MB.     Data is not secure. Additional effort need to secure data stored 2. Local storage     Local storage is also a very well-known storage. This is u...

Polymorphism in Java OOP

Image
Polymorphism is word made from two words "Poly" which means many and "morph" means shape/form. Polymorphism means "ability to take multiple shapes or forms". In Java, method and Object both takes multiple forms. There are two forms of polymorphism : Compile time Polymorphism Run time Polymorphism Compile time polymerphism Compile time polymorphism is achieved using method overloading. Method will have same signaturre(name) but different parameters.This method is bound statically with method name and input parameter type hence static binding. Output : Display String Display int Runtime Polymorphism Method overriding is used to achieve Runtime polymorphism. Method will be overridden in subclass. This method is resolved depending on Object instance dynamically at runtime. Output : Display of Display Unit. Display of Monitor.
