size of int in java code example

Example 1: java how to find length of int

int x = 1234; 
int lengthOfInt = String.valueOf(x).length(); //convert integer to String
											  //and get length of the String

Example 2: how to get length of integer in java

int length = (int) (Math.log10(number) + 1);

Example 3: java int to hex fixed length

//You can replace X with x to get lower case hex characters
//Replace the 2 with the amount of digits you want
String.format("%02X", value);

Example 4: 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

  unsigned long long int = 18 446 744 073 709 551 615

Example 6: what is primitive data type in java

Primitive types are the most basic data types available within the Java language. There are 8: boolean , byte , char , short , int , long , float and double . These types serve as the building blocks of data manipulation in Java. Such types serve only one purpose — containing pure, simple values of a kind.
