BYTE DATA TYPE JAVA code example

Example 1: all data types in java

Data Type	Size	Stores
byte		1 byte	whole numbers from -128 to 127
short		2 bytes	whole numbers from -32,768 to 32,767
int			4 bytes	whole numbers from -2,147,483,648 to 2,147,483,647
long		8 bytes	whole numbers from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
float		4 bytes	fractional numbers; sufficient for storing 6 to 7 decimal digits
double		8 bytes	fractional numbers; sufficient for storing 15 decimal digits
boolean		1 bit	true or false values
char		2 bytes	single character/letter or ASCII values

Example 2: primitive data types in java

/* 
	Java Data Types
There 2 Types Of Data Types In Java
1) Primitive -> byte, char, short, int, long, float, double and boolean.
2) Non-primitive -> (All Classes) -> String, Arrays etc.

Type	Size	Stores
byte	1 byte	whole numbers from -128 to 127
short	2 bytes	"" -32,768 to 32,767
int	    4 bytes	"" -2,147,483,648 to 2,147,483,647
long	8 bytes	""-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
float	4 bytes	fractional numbers; for storing 6 to 7 decimal digits
double	8 bytes	fractional numbers; "" 15 ""
boolean	1 bit	true or false values
char	2 bytes	single character/letter or ASCII values

Example 3: class as a data type in java

Class Node {

Node next = null;
int data;

public Node(int d){ data = d; }

void append(int d)
    {
        blah blah blah
        ..............
    }
}
