Java technologies should be treated like mathematics. As much you will practice as much you will gain.

It needs a lot of confidence on and patience in ourself to get a development job. I have live examples. My friend learnt all the technical skills required to grab a developer job. I was also guiding him. He was clearing technical rounds in interviews. The one thing lead him to do a telecommunication job is lack of confidence, patience and less faith on his own. Telecommunication is also a great field with opportunities. It is true that getting late in first job makes tense. But if we are able to get a software development jobs then why are we in hurry. Hope plays always and build confidence in you. Please do not loose your hope.

Eat heathy foods and do proper excercise.
