Many times it is important to write output to a file to be saved. This is commonplace in just about every kind of Java application - from business to games. It allows the users information/status/progress to be saved or recorded for future reference. In order for this to work, the simplest solution is to create a file in the same folder as the Java program. For this example, we are going to create an output file called output.txt.

There are times when it is necessary to accept input as a string, yet you may need to take a value from that string and convert it into an integer for calculations. This is a very common practice in Java programming.

This tutorial will teach you how to create a blend effect in your windows form or a transparency/opacity of the form using vb.net. This will use "user32" library of our computer system so that it will take effect. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2. Create only a Form in your project. Insert also a Timer on it.

This tutorial covers creating a calculator to convert between Celsius (centigrade), Kelvin, and Fahrenheit. The user is first given the choice of which temperature unit they would like to convert from, and then they are given the results of the conversion. When different units are in use, things can get confusing. It is useful to have a calculator on hand for this sort of thing. Luckily, we can make one in Java that is able to do just that.

Previously, we covered how to use arrays in Java. If you are unfamiliar with arrays, please read through the first tutorial on arrays here. Two dimensional arrays are used to hold numbers that correspond to one another. One dimensional arrays can be thought of as a collection of variables listed in an indefinite number of rows, but a single column. Two dimensional arrays allow for both indefinite rows and columns.
