Notes for You:: Java program to find Size of all Data Types - Java Tutorial 09

Data type:
- indicates type of data.
- also indicates the amount of memory to be allocated for a specific type of data.

There are 8 primitive types available in Java language.
1. byte : 08 bits - 1 byte
2. short : 16 bits - 2 bytes
3. int : 32 bits - 4 bytes
4. long : 64 bits - 8 bytes
5. float : 32 bits - 4 bytes
6. double : 64 bits - 8 bytes
7. char : 16 bits - 2 bytes
8. boolean : 1 bit

- To find and print size of any primitive data type; we take help its associated wrapper class.
- Inside each wrapper class (except Boolean type) there is a SIZE property; which returns the amount of memory being allocated for that specific type of data in bits.

Example Code:
package sizeofdatatypesdemo;
public class SizeofDatatypesDemo {

public static void main(String[] args) {


}

}
