Data types

Java | Data Types: Java data types are strings, numbers and boolean values.

---

One by One:

Strings:

        The strings are nothing but collection of characters and also text is in between double quotes.

        

Numbers:

        The numbers are sub divided into int, float, double and long.

        Ex: 10 is int, 3.14F is float, it takes up to 7 decimal positions, 2.414343 is double, 

        it takes up to 15 decimal positions and 1234565432112345L is long

Boolean:

         There are two boolean values, those are true and false.

Here is the Code:

1. import java.io.*;
2. 
   
3. class Main {
4. public static void main (String[] args) {
5.      // String
6.      System.out.println("cool");
7.      // Integer 
8. System.out.println(1);
9. // float takes up to 7 decimal positions
10. System.out.println(3.1421242323243554545F);
11. // double takes up to 15 decimal positions
12. System.out.println(2.4143245423242342321);
13. // long 
14. System.out.println(12345432123454321L);
15. // boolean
16. System.out.println(true);
17. }
18. }

Output:
