LabExer#37

37. Develop program that has the following methods: ODD(), EVEN(), NEGATIVE(), POSITIVE(). Each method will be visited in order
of sequence as above stated. Every visit will print the string or word the same name of the class if the number entered is TRUE.
Otherwise, no value is returned or NULL. Then, call each method until it reaches the method name POSTIVE() will then stop the
whole process and display the final output.

Example#1:
Enter a number: 3
3 is ODD POSITIVE

Example#2:
Enter a number: -4
-4 IS EVEN NEGATIVE
