For starters, double is bigger than float.
Double is also the default type for primitives with a decimal point. You can read about each of them in the tutorials and finish up the list of their differences on your own.

this is a good tutorial on the java primitive data types
http://java.sun.com/docs/books/tutorial/java/nutsandbolts/datatypes.html

also
http://en.wikipedia.or g/wiki/IEEE_754#Single-precision_32_bi t

in practice you analyse the data you are using in the application and select the most appropriate data types. for example if the data inputted is accurate to 3 or 4 siginficant figures use a float (typical precision 6 or 7 significant figures) - no need for the greater precision of double and calculations in double take longer than float
