Hi have done MCA 2 years ago I have to make a career in java but one prob with me is that I am 32 years old and there is a huge gap in my education. what would be troublesome and what should I do?

Start it now instead of wasting time to think about. In a month you will get familiar and start recalling what you have already learnt. Two years is not a long period. I did it after about 10 years of my education

Java is an object-orientated programming language, which was originally developed by Sun micro systems. When you combine the two, you get a Java Developer.
