Java is a programming language with which we can make any type of program. At present, it is a very widespread language and is becoming more important both in the internet and in general computing. It was developed by the company Sun Microsystems with great dedication and always focused to cover the more advanced technological needs.
One of the main features for which Java has become very famous is that it is a platform independent language. It means that if you make a program in Java, it will work on any computer available. It is a significant advantage for software developers, because in the past they had to do a program for each operating system separately, for example, Windows, Linux, Apple, etc. This is achieved because a Java Machine has been created for each system that acts as a bridge between the operating system and the Java program and enables the latter to be perfectly understood.
Platform independence is one of the reasons why Java is interesting for the Internet, since many people must have access with different computers. But it does not stay there, Java is developing even for different types of devices besides the computer as mobiles and in general for anything that occurs to the industry.
Past and Present
Java was originally intended for use in any type of appliance, but the idea failed. One of the founders of Sun Microsystems rescued the idea to use it in the internet and made Java a powerful, safe and universal language, thanks to the fact that it can be used worldwide and it is free. One of the first triumphs of Java was that it was integrated into the Netscape browser and allowed to run programs within a webpage which was unthinkable with HTML.
Currently Java is used in a wide range of possibilities and almost anything that can be done in any language can also be done in Java and many times with great advantages. For what we are interested in, with Java we can program dynamic web pages, with access to databases, using XML, with any type of network connection among many systems. In general, any application we want to do with web access can be done using Java.
Java is so big that if we want to do complicated things, you might not be able to learn everything, so all you can do is keep learning and this blog will keep helping in you in this regard.
Looking ahead to the installation of Java with Windows Operating System may be slight different depending on the version you use i.e. Windows 10 or higher, Windows 8, Windows 7, Windows Vista, etc. First of all, you have to double-click on the Java installer file, which you will have downloaded previously named jdk-8u72-windows-i586.exe or similar.
An initial installation window will appear, informing you about the conditions of the license. Once you have read, continue the installation by clicking on the “Accept” button. In the window that appears below, the first thing to look at is the installation path (“Install to:”). This is the address where Java will be installed; it has the default route. If you do not agree with this route, you can change it with the “Change” button. As a recommendation, I advise you to avoid changing it if you do not have advanced knowledge. The reason is that many programs working with Java recognize that route by default. So keep it for avoiding the problems and having to be configuring the route to be used by other programs.
In the middle part, it indicates options for what you can install i.e. Development Tools, Demos and samples or test samples, Source Code, and Public JRE or set of Java utilities. You can choose to install certain parts of Java and leave without installing others. To save hard disk space, you may not install certain parts of Java such as test samples, which you can do by deselecting those unwanted options. If you do not have space problems, it is advisable to leave everything as it is and consignee installing all the options. Having said that, now you click on the “Next” button and continue the Java installation.
Without having finished the process of the previous window, another window will appear, something similar to the one that showed you the default route in which the Java environment will be installed. The environment is recognized by a name such as “jre8” or similar, present at the end of the route. Following the same criteria discussed above, it is a route already recognized by default by many programs that require Java Virtual Machine. To avoid route configuration problems, it is preferable that non-advanced users do not make any changes. If you still want to, you can use “Change” button and continue with the installation, clicking the “Next” button.
If all goes well, a window will appear indicating that the installation is complete. Click “Finish” to finish the installation.
