java int size code example

Example 1: java get screen size

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();

// the screen height
screenSize.getHeight();

// the screen width
screenSize.getWidth();

Example 2: 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 3: 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.

Example 4: byte size 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
