Introduction to Java
This is among the popular programming languages today because of its compatibility and versatility feature. The coding language can be employed in different things ranging from software development, large systems development and also in mobile applications. Currently, a huge market share of the mobile operating system and all smartphones running on Android have been written in Java. Gaining an understanding of the basics of java is many doors for all developers in the market.
The frameworks to use with Java
Java being the general purpose language is an excellent thing about it; it has been employed in various environments. Java’s explicitly is intended to operate on many different platforms. It can be operated on your windows, your cell phone, the Linux machine, Mac or the UNIX box. Java can actually be employed with about anything at large. Java virtual machine download windows 10 will allow any Java written program to be easily run on your PC by compiling it into Java bytecode.
Some ways of reading files
Use buffered reader
Employing this method helps in reading texts from a stream of character input. Buffering is done to ensure there is an efficient reading of different arrays, characters, and lines. The default size of the buffer may be used or specify the buffer size you need. But then, the default size is large enough for different purposes. To sum up this idea, every read request that is made for a reader causes a read request corresponding that should be made to the byte stream or underlying character.
Use a file reader class
This is a convenient way to read all the character files. This class constructor assumes that character defaults encoding and the size of byte-buffer are all appropriate.
Use scanner class
You can also use a simple text scanner to parse primitive strings and types by employing regular expressions. In a delimiter pattern, the scanner breaks all input into tokens that match whitespace by default. Values of different kinds result right from the conversion of the tokens using different methods in place.
How to uninstall Java in windows
To ensure you have accomplished this, first remove all other older versions and after that go to the control panel, then to the programs and finish with the features. Follow up by clicking on the latest version of java that has been listed and complete by clicking uninstall.

It will show you right on the first screen that the uninstaller wasn’t detected, this is good as all java versions were uninstalled. What you need to do is clicking on the next button.
Tips for writing a nice java code
For those who are new in the programming knowledge, coding java in the best way possible is not easy as you may think. As a beginner, you will probably encounter many problems until you achieve what you are looking for. To some, they might even get frustrated at the end. Below are some best habits you should employ to make your entire code writing process;
Use comments- What are the comments? These are simply short written statements that will guide you and other people what and how your code is and the thing that is supposed to be done.
Build small classes- By doing this, your code will all times remain maintainable, readable, clearly accessible to all other developers who will be needed to deal with it after you complete working on it.
Name all your methods clearly- Naming of the methods helps in preventing things from falling into confusions, this is more especially in case you are writing complex programs with many different lines of code.
These are among the things that a beginner can do to ensure to help get the best writing code right from the start to the end. For this stage, there is a need you to get out and get to know how to do the right thing possible. Get to know more about java for you today.
