I am really thinking hard to understand why java has introduced new concept called Lambda Expression in its 8th version.

I mean as far as I understand it is just like a regular function which calculates an expression and returns the value. Is there anything that a lambda expression does beyond this and what exactly happens behind the screen. Please educate me!!!

Thanks in Advance.!!

    "Is there anything that a lambda expression does beyond this ..." - Nope. " ... what exactly happens behind the screen." - Look at the bytecodes, using javap. "Please educate me!" - That's your job ... or your teachers. Commented Oct 29, 2014 at 3:00

    The other point of course is that Java doesn't have functions, per se. It has methods. Commented Oct 29, 2014 at 3:04
