Java

Hi Rati,
Both are good, but if you are thinking of only jobs, CCNA certified people are given preference.
In java, you have to think of algorithms and syntax to apply the logic, you don't have to understand much but you have to think much. As for the CCNA-CCNP, its purely networking. It have less syntax but more thinking and understanding. It consists of network designing. You have to design networks between devices and make them communicate each other. The more you can imagine, the more you will learn.

Pankaj, I am not sure how good you are with maths and programming. If you are, then you must pick up Programming and take a language whether PHP/ HTML5 (web dev), .Net (for software dev) Java/ Android (for apps) or C#/ Unity (for games). However like i mentioned, you must be good with programming to move ahead in this area since you have to compete with MCAs and BTech(CS) applicants. So choose your internship/ industrial training very carefully. Do not just go for the cheapest to save money. See the IT company's credentials on the net. for example if someone provide LIVE PROJECTS are they there near the TOP on PORTALS like JUSTDIAL? Or if the company is registered with STPI (Software Technology Parks of India) - all good IT companies are registered with STPI. If a company spends money to market themselves to customers, only then they are able to get LIVE PROJECTS. Also, if you are an average programmer, and if you you're better with creative work, then you can head for web design or even vfx/ animation since there is a huge requirement coming up in that domain. There is also an intermediate path in games design and development. Wish you the best for your career. Remember, your Career is a resultant of your knowledge combined with your passion and expression ability. If you like this answer you may select it as best answer or press like.
