Top tips for Fine tuning Java Performance in Programming

For last decade Java has shown tremendous ability to cope with changing trends and future adaptability for use in building large scale applications. It is also highly scalable and used for developing complex architecture in internet based prototypes as well. Hence there are best practices that we must implement for getting high performance in output through Java programming.

Planning:

Every project begins with few ideas that must are put together for larger and complex system of operations for leading into whole network. So as programmers you must be prepare to plan your work and estimate the timing that will allow you to reach the project in specific timing. Create short goals and targets for days, week and months that correspond to finishing the project on time. Testing is another fundamental which must also be added to your overall programming time giving you the ample time to check your code on multi platform-browser devices for better user experience.

Identify the crux of the whole application:

In live projects there will be few points that will are the crux of the whole application as a developer you need to act smart and take initiative for generating creative solutions that can lead to faster results altogether. As these might create few delays you should prepare your code around it and must plan to tackle this part of the coding with right approach and minimizing the time respectively. Also check out Java Programming for Beginners that are perfectly matched for fresh graduates in delivering the best performance from them.

Interacting with Databases

One of the biggest problems that developers have faced over the year while developing Java based application is interacting with databases. One must adhere to best practices in making sure databases are correctly used as per the required processes. One must create pool of connections with objects that must return to the connection object of the pool for reusing avoiding overheat spent for initialization and authentication processes from servers when thread is required to store data from client side respectively.

Network Architecture

For reliable performance you must understand the current network architecture with complete topology understanding of its capability and maximizing the performance. High Volume database servers are recommended to meet the demand of the continous queries being propelled form front end. Necessary high bandwidth must be allocated smoothing the data flow for whole operational process.

Creation of Object

Creating too many objects can lead to excessive memory churn and pauses from Garbage collection as well.  One must program with clean code utilizing the architecture that result in high performance always. Memory use for objects must be set aside which must be reclaimed when the Java object is released respectively.

One must also use best practices for coding those results in fine tuning coding in Java programming. Creating new strings again and again must be avoided while using flexible objects in recommended. Threads must be implemented as per the requirement without destroying and creating them recurrently. Mock variables must be used in checking the real time functioning of the whole operations. CPU load must also be checked for each transaction avoiding  high loads for better performance.

Although Java offers a lot of choices there are lot of hurdles and challenges that remains in the course of developing high performance application. Over the years continous use and with experience will let you use the Java for better user experience. Javatutorialpoint is one such online platform where users come to read the most cohesive written that will teach you all the fundamentals of Java Programming. Above written tips should be written should be implemented in your code once you get the idea of coding respectively.

ADVANTAGES OF JAVA SERVLETS

Java Servlets are the middle layer program between server and database between the HTTP servers which is activated when there is request being called from web browser. Although they can answer any type of service request but most comes from web servers commonly. They in turn act as the extended part of Servers as Java Programs only. You can also go through Servlet Tutorial For Beginners that are written for teaching the new learner with examples and offers complete support for daily guidance as well.

Before this concept of Common Gateway Interface was used for enhancing server side capabilities but Servlets with new technology have emerged more superior over them which led to huge rise in terms of usage among web applications.

Main advantages that Java Servlets have over CGI are mentioned below:

  1. Java Servlets are extremely portables with basis on writing once, run anywhere (WORA) program. If you have developed Servlets on window machine with tomcat server then the same program can be used again UNIX based OS giving multi platform compatibility. This property is possible because these programs are all written in Java and uses standard API protocols within themselves.
  2. Java Servlets are highly scalable and efficient as multiple requests are being able to run individual threads whereas CGI Scripts used lot of speed and memory resources for simultaneous requests adding in the time and service delay to the user.
  3. These Servlets can be easily written within the use of Java APIs plus you can count upon for cookie handling and session tracking much better with this Java components.

4.Earlier used CGI programs were not able to communicate directly to web servers for sharing data but these new Java Servlets technology makes easy connection with databases with session tracking they are able to store all information request to request.

  1. These Servlets are completely server side component which has complete web server security. Moreover they are also secured by using Java Security Manager.
  2. Servlets are also protocol independent services being able to support any protocols like FTP (File Transfer protocol), NNTP, and Telnet Sessions etc.

7.Java Servlets have more handling capabilities than CGI scripts which were written in C++ that if used for exceptions might cause web server to crash like divide by zeros conditions whereas in Java Servlets uses exception to handle these errors more sophisticatedly. Servlets also have the capability to access J2SE and J2EE with Java Programming language results in better dynamic solutions for website. They also enable smooth transition between web servers and respective Operating systems.

If you could all these points in one go Java Servlets have powerful fundamental architecture, performance, secure, flexible and overcome most of the disadvantages that were made by CGI scripts.
