Java DataTypes – primitive & non primitive

DataType defines a particular kind of data or value it can take

Primitive DataType: 

Primitive means “very basic”.

In Java, primitives are the most basic kinds of data types and they directly contain values like int, char etc.

NonPrimitive DataType: 

Non primitive datatypes are those which uses primitive datatype as base like array, class etc.

Also called as reference types which references a memory location where the data is stored rather than directly containing a value.

Classification

Primitive types –

package mypackage;
public class DataTypeSample {
	public static void main(String[] args) {
		int myInt = 234;
		System.out.println(myInt);
		
		System.out.println("Int size - " + Integer.SIZE);
		
		char myChar = 's';
		System.out.println(myChar);
		System.out.println("Char size - "+ Character.SIZE);
		
		boolean myFlag = true;
		System.out.println(myFlag);
		
		float myFloat = 2.333f;
		System.out.println(myFloat);
		
		double myDbl = 3.44444;
		System.out.println(myDbl);
	}
}

Output –

234
Int size - 32
s
Char size - 16
true
2.333
3.44444
