States of a Thread

 States of a thread

New: When thread is created, it will go to the new state.

Runnable: When we call the start() method, then thread will go to the Runnable state, If multiple threads are created and for all the threads if start() method is invoked, then all the threads will go to the Runnable state.

Running: Under Running states, there are 3 sub-states. and under Running state at a time only one thread will be present. It depends on the thread scheduler which thread it schedule.

i) Sleep: when sleep method is called, then the thread will go to the Sleep state.

ii)Blocked: When the requested resources are not available, then the thread will go to the Blocked state.

iii)Wait: When wait method is invoked, then the thread will go to the wait state, and again when we call notify() or notifyAll(), then again it will go back to the runnable state 

Dead: When the thread life is completed, then it will go to Dead state.

Terminologies associated with Debugging a. Bugs => Problem/defect/mistake in the app/program/project[some abnormality in the application execution] Debug = > De + bug [Rectifiying the bug by identifying and Analyzing the bug] The tools or programm or software that can be used for debugging is called "Debugger"/Debugging tool To debug java code we have two tools a. JDB(Supplied by jdk tools with jdk installation) => available inside <java_home>\bin directory as jdb.exe => it is CUI tool and not so popular(Not industry standard) b.

Advantages and Disadvantages of Monolithic Architecture

 Benefits of going for Monolith Architecture  Simple for development(becoz all are available in single project): At initial time it is very easy.   Easy for Testing : End to End Testing we can perform.   Easy for deployment : One war file only we have to deploy to server.   Easy for Scaling : multiple server we can spin easily(horizontal/vertical scaling) if requests increases then we can make keep multiple servers through which the scaling can be done to provide good responses to the client.  Disadvantages of Monolith Architecture  Maintenance of the application: If the application is to large and complex, it is difficult to understand. Change Request in the code is very difficult. Some changes in the existing application will have an impact to the other code, Lot of Impact Analysis will occur.   Adapting to New Technology is required: Change in java version and adapting to the version change also will take time. Applicati...
