TeenNumberChecker.java

// Write a method named hasNotTeen with 3 parameters of type int.

// We’ll say that a number is  “teen” if it is in the range 13..19 inclusive, otherwise it is not teen. Given 3 int values, return true if none of them are teen, otherwise return false..

// Example 

// Sample Input 1 :

// 13 12 20

// Sample Output 1:

// False

// Explanation:

// Since 13 is a teen number, hence false is returned.

 

// Sample Input 2:

// 9 29 21

// Sample output 2:

// True

// Explanation:

// Since numbers 9,29,21 are not in range 13-19, hence true is returned.
