java numeric data types 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: 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.
