I want to that why in java we can't do type casting from higher datatype to lower dataype.I mean
float f=2.45f;
int i=(float)f;

What exactly happens here at at memory level.Is it because of the two different way bot the data type are represented internally.If yes.. can someone pls explain it.

Please note that you are not doing a cast from a float to an int, you are just trying to assign a float to an int.

The correct option would be:
int i=(int)f;

And then i=2.
I agree. Here's the link:
