Java's primitive data types are
boolean
char
byte
short
int
long
float
double
Number types (both integer and floating point types) are all signed.
For integer types the sequence from small to big is byte, short, int, long.
doubles are bigger than floats.
boolean can be only true or false.
The char type contains a single, 16-bit Unicode character.
public class MainClass{
public static void main(String[] argv){
byte b;
short s;
int i;
long l;
float f;
double d;
char c;
boolean bool;
}
}
