Question

What is the difference between data types and literals in Java?

Answer 1

 String string = "Hello World";
 <  1 > <  2 >   <     3     >

1 is a data type, 2 a variable name, 3 a (String) literal

From the JLS:

A literal is the source code representation of a value of a primitive type [like 1, true, 't'or 1.2f], the String type [like "" or Something], or the null type [null]
