Odd and Even Numbers in Java Using One Dimensional Array

About this program that I wrote it will ask the user to enter a series of integer number and then the number is being stored in one dimensional array. Our program will enumerate the odd and even numbers based of the numbers given by our user.

Bubble Sort in Java Program

In this article I would like to share with you one of the most common sorting algorithm used in computer science it is called bubble sort. Basically we use sorting to arrange the values in ascending or descending order. What our program does is to ask the user how many items to be sorted and then our program will ask the user to enter a series of values. After which our program will display the original values and it will display the ascending and descending order of values after it is processed by our program using bubble sort algorithm.

First Letter Capital Program in Java

As I continue my study on Java I have discovered that Java programming language has many built in functions that makes programming much easier and more fun specially we are working with strings. I enjoy every minute working with Java. No wonder there are many programmers, developers and software engineers find it very useful in many programming project because it is a very versatile programming language.

In this article I would like to share with you guys a sample program that I wrote in Java that will ask the user to give a sentence and then our  program will convert the first letter of the sentence into uppercase letter. I have created a method on it that well convert the first letter of the word in a give sentence by our user.  In addition our program it will ask the user if the user would want to repeat the program running by asking the user do you want to continue yes or not.
