Welcome to the Interactive Java Tutorial. Primitive types are the most basic data types available within the Java language. Boolean and null primitives: boolean and null. All the primitive types have a fixed size. Thus, the primitive types are limited to a range of values. A primitive type should be set by an appropriate value.
The primitive types can be initialized with a literal. Most of the literals are primitive type values, except String Literals, which are instance of the String class. Programming may not be as trivial or boring as just crunching huge numbers any more. However, huge chunks of code written in any programming language today, let alone Java, obsessively deal with numbers, be it churning out huge prime numbers, or just calculating a cost of emission from your scooter.
Numbers are stored in memory using a binary system. Actually, each cell does contain a binary digit, as one bit is roughly equivalent to 1 and an empty cell in the memory signifies 0. A single binary digit can only hold two possible values: a zero or a one. Multiple bits held together can hold multiple permutations — 2 bits can hold 4 possible values, 3 can hold 8, and so on. So, the numbers from 0 to 255 can fit within 8 bits.
Unsigned integers are whole number values that are all positive and do not attribute to negative values. This leaves us with just 7 bits to actually count out a number. Not a bad pay-off one might presume. The opposite to an unsigned integer is a signed integer that have the capability of holding both positive and negative values. You would need significantly more bits to hold larger numbers.
