Highest and Smaller Number in Java

One of the most interesting problem in programming is to ask the user to enter a series of number and then our program will determine which of the given number is the smallest and the highest number from the series of number by the user. Normally the data structure that we will use in this problem is array to be specific one dimensional array so to speak and then we will use for loop statement and if statement to compare each numbers and to check which of the given number is the smallest and highest.

I called this program Highest and Smallest Number in Java what the program does is to prompt or ask the user how many numbers to be accepted and to be process. After the user provide the values in our program it will compare and determine what is the smallest and the highest in a given list of values.

The program is very simple and easy to understand. I hope you will find my work useful in learning how to program in Java. If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.
