The ever evolving world of application has undeniably brought the JAVA platform to limelight with most of the communication oriented applications like Skype Lite, eBuddy IM Service, Gmail for Mobile, Google Maps being developed using JAVA programming. Well with every cause there is an effect. This alarming rise of applications has created opportunities for enterprises with core business focusing on application development to either directly hire JAVA developers or outsource JAVA developers from India.

Robust application development in JAVA calls for specific domain expertise, thereby creating opportunities for people who are proficient in the emerging frameworks. JAVA programming is all about defining classes and creating objects. The quintessential criteria in selecting the correct developers in his ability to write better code with fewer bugs thereby, reducing the development time.

Three major development challenges that every JAVA developer should know

• Memory leaks: This issue typically results from using older languages that requires a manual clean up of memory. Heap dumps build up when a developer does not clean the references to an object resulting in an application coming to a halt. In the case of JAVA, there is a memory model that manages the heap dump for every used and unused reference and the creation of these heap dumps allow to analyze memory leaks.

• Slow SQL: This issue results from too much of data being fetched and not being indexed. This slows down the SQL performance. Another reason for a slow SQL would be Object Relational Mapper or ORM. The use of ORM eliminates the analysis of how two technologies interact using a relational database. However, the use of ORM can place significant burdens on the applications thereby impacting the functioning of SQL.

• Threading/Synchronization: This issue arises from the lack of synchronization with JAVA support. In JAVA, the codes are executed in separate threads within the same process, thereby sharing the same resource and object in memory. This often poses interference and consistency problems. To avoid such a situation, a developer needs to understand the criticality of using the keyword ‘synchronized’ for every thread execution.

Wondering how to hire a JAVA Developer, here are some important insights:
