Just wondering...

Hi.. I just want to ask something.. all the videos that i watched from this part of the course is that Sir Craig is using data types that are mostly int and Strings .. and if the string is being "called" on the String sample = "sample string"; System.out.println("This example %s",sample); the %s indicates that, that is a String..but how about for Float? how does the float differ from the String ? thanks ... I'm just a newbie here :D

Hi Albert,

The float data type is a single-precision 32-bit IEEE 754 floating point. Its range of values is beyond the scope of this discussion, but is specified in the Floating-Point Types, Formats, and Values section of the Java Language Specification. As with the recommendations for byte and short, use a float (instead of double) if you need to save memory in large arrays of floating point numbers.

Strings, which are widely used in Java programming, are a sequence of characters. In the Java programming language, strings are objects.

You may want to read the following for a deeper understanding of primitive data types and Strings in Java:
