Java variables

Java variables


Here is a list of all primitives in Java:
byte (number, 1 byte)
short (number, 2 bytes)
int (number, 4 bytes)
long (number, 8 bytes)
float (float number, 4 bytes)
double (float number, 8 bytes)
char (a character, 2 bytes)
boolean (true or false, 1 byte)

EXAMPLES :

To declare and assign a number use :
                 int number;
                number=2;                     or you can directly use :    int number=2;

For Float :
              float f = (float) 5.5; or you can use: float f = 4.5f; 


For Char :
             char c = 'hello';

For String :
            String c ="hello programmers" ;

THIS IS THE JAVA VARIABLES.
