Product of Two Numbers in Java Using Scanner Library

In this article I would like to share with you a very simple program that I wrote in Java I called this program Product of Two Numbers in Java Using Scanner Library. I am just a beginner in terms of using Eclipse Java IDE text editor while I'm learning how to create a project I just wrote this very simple program that will ask the user to enter two numbers and then it will display the product of the two numbers to the user.

I find the eclipse ide editor easy to use and user friendly in a sense it display a command while you are type your code it is called intellisense function that can be found in Microsoft Visual Studio.

I hope you will my work useful and learning Java programming. If you have some questions feel free to send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

People here in the Philippines who wish to contact me you can text or call me at this number 09173084360.

Thank you very much and God Bless.

Scanner scan = new Scanner(System.in);
System.out.println("Product of Two Numbers");
System.out.print(" Enter first value : ");
int val1 = scan.nextInt();
System.out.print(" Enter second value : ");
int val2 = scan.nextInt();
int product = val1 * val2;
System.out.print("The product of "+ val1  + " and " 
+ val2 + " is " + product + ".");

Area of a Circle Using AngularJS

In this article I wrote a very simple application using AngularJS as our Javascript Framework that will solve the area of a circle by asking the user to enter the radius of the circle.  The code is very simple and straight forward. I am still a beginner in AngularJS programming as this moment I find it very easy to write and test our sample program.
I hope you will find our program useful in learning how to program using AngularJS one of the most popular Javascript Framework in our community right now. If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

People here in the Philippines who wish to contact me can reach me in this mobile number 09173084460.

 Thank you very much and God Bless us all.
