long integer in java code example

Example 1: range of byte data type 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: java long to int

public class LongToIntExample2{
      
    	public static void main(String args[]){
          
        	Long l= new Long(10);
        	int i=l.intValue();
        	System.out.println(i);
    	
        }
    }

Example 3: java long to integer

// auto-unboxing does not go from Long to int directly, so
Integer i = (int) (long) theLong;

Example 4: 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
        ..............
    }
}
