Write a program to demonstrate Variable declaration and datatype. Use all the Primitive datatypes.

public class NewClass {
     public static void main(String args[]){
         System.out.println("Rocktheit.com");
         long num1 = 1234567890;
         System.out.println("Long Data Type :"+ num1);
         int num2 = 1234567890;
         System.out.println("Integer Data Type :"+ num2);
         short num3 = 12345;
         System.out.println("Short Data Type :"+ num3);
         byte num4 = 123;
         System.out.println("Byte Data Type :"+ num4);
         double num5 = 4.567890;
         System.out.println("Double Data Type :"+ num5);
         float num6 = 1.55f;
         System.out.println("Float Data Type :"+ num6);
         char var = 'K';
         System.out.println("Char Data Type :"+ var);
         boolean bool = true;
         System.out.println("Boolean Data Type :"+ bool);
 }
 }

Output:

Rocktheit.com
Long Data Type :1234567890
Integer Data Type :1234567890
Short Data Type :12345
Byte Data Type :123
Double Data Type :4.56789
Float Data Type :1.55
Char Data Type :K
Boolean Data Type :true
