Java is one of the most popular programming languages out there and it was created way back in 1991 but it was publicly released only in 1995. Java is a write once run anywhere type of programming language which means that everything which happens in java happens around objects objects enable the execution of the program. Java can be used to build web applications mobile applications desktop applications even command line applications. Java is a strongly type checking language so when you run your program it 's a two-step process in java you compile the program and then you it then you execute the program which we also call as interpretation so you have a java compiler and a java interpreter. Java also provides automatic garbage collection and multi-threading support. Java program can be run on any machine let 's take the example that you ran these two steps on a windows machine so you ran your you write your program and you compile your program. Once you have the bytecode available then you can run this program on any other platform of your choice okay so that was about how the java program execution works.
We will basically look at how we can install java on a windows machine using jdk. The first step to install java is to download it from the official oracle website. You can also install gre separately if you talk about that use case where you compile your program on a. windows machine with jdk and then you exported your dot class file to another machine and there you just installed the. runtime environment. In terms of what platform you want to install java on whether it is a linux platform or a mac os machine or a windows platform so like i said in the beginning of the demo that today we are going to see how we can install this on a windows machine. i 'm going to download the windows x64 installer here if you are working on a linux machine or macos machine you can download those respective installers as well so you can see the exe here. Java is going to unpack all the all the libraries and all the runtime libraries which we discussed in the previous lecture and put all that into the location which we specified to install java it will also set up the rest of the prerequisites which are required to run java successfully so looks like the java has been successfully installed. If you get a message saying that java is not recognized as a command it means that Java is still not successfully installed and something has gone wrong in your installation.
installing eclipse on a windows machine so the first thing which we need to do is to download eclipse so for that i 'm just going to open my web browser and type eclipse download press enter and then you need to find the link which says eclipse. org downloads which is the first link in my search results. Eclipse is an open source organization it works on donations so if you feel generous about it you can also donate to it which will show here so we can move to the next step which is about installing so you can see here i have an installer here an exe file basically which i have pre-downloaded to showcase this demo. use that exe to showcase how we can install it. The installation generally takes a bit of time to complete in some cases so again it depends upon your in your computer's capacity and speed. If you have a computer which is not very strong on configurations you can just be patient and wait for some time and the installation will be finished once the installation is finished you will see this launch option here.
