Checking if the given number is already sorted in Java

About this program it will check if the given list of numbers stored in one dimensional array is already sorted or not using Java. It will return if the given list of numbers is already sorted and false is the given number is not yet sorted.

I hope you will find my work useful and beneficial. If you have some questions about programming, about my work please send mu an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com. People here in the Philippines can contact me at  my mobile number 09173084360.

Thank you very much and Happy Programming.

Odd and Even Number Checker Using Scala

I wrote this simple program to ask the user to give a number and then our program will determine if the given number by our user is an ODD or EVEN number. I am using Scala as my programming language in this sample program. I am still a beginner in Scala programming, learning Scala is much easier it resembles Java programming language in many language syntax and features. I hope you will find my work useful. Thank you.

Hello World in Scala

This will be my first time to write a code using Scala my very first program is a simple hello world. Scala is much similar with Java it is also object oriented programming language and functional programming language. I am still exploring and experimenting on this language which I found very interested to learn and use. I hope you will my simple work useful. Thank you.
