First, we need to visit the official Oracle download page and choose the right release for the Java SE Platform. Bear in mind that Oracle has dropped the support for 32 bit systems.
As a result, we can use Java SE only in 64 bit machines. For instance, Oracle offers two options to install Java on Windows: through a. Basically, the process of installing Java on Windows 10 is pretty easy and simple. Firstly, we need to double click on the downloaded installer file to start the installation process:.
However, we can always change it if we want that. Finally, we close the installer window once the installation of JDK is complete on our Windows The basic idea behind setting the Java Path is to make all the Java commands like java, javac… accessible from everywhere.
Under system properties, go to Advanced Tab. On the bottom, you can find a button with name ' Environment Variables.. Just click. Under Environment Variables, you can see two sections. The top section shows User variables and the bottom section shows System Variables.
These libraries are predefined or supplied by a third party vendor to enhance the functionality of a Java Application. Software companies develop their own libraries which are packed as JAR files that can be used by different projects. The advantage of adding Class path in command prompt is that you can include or add different libraries for different projects. This approach is not recommended as you can not have different libraries for different projects.
Libraries required for one java project may not be required for another java project. Including unnecessary libraries consume memory and affects performance.

Add Java 1. Per David's suggestion, the following is the Java related contents from the output of command PATH the entire output is super long, I hope the following is sufficient for this question. I noticed that after checking the path per your suggestion. Windows 10 does not allow me to edit the path because it says "This environment variable is too large. Check also registry. Press Win key-R, type regedit. If there is something different, than you expect, than it is better to reinstall Java.
If it not possible, very carefully change the settings. Be aware, that from version to version the setup can be different. In my case I would to downgrade from Java 1. After reviewing the other recommendations, I still found Windows 10 to be running the wrong version of Java. The correct version of Java ran in a command shell, but Windows would not start an application with the correct version of Java. In my system, there was yet another entry in the Registry.

The best answers are voted up and rise to the top. Sun came to realize, around Java 2, that this environment setting is unreliable, as users often set it incorrectly, and unnecessary, as it's easy enough for the runtime to find the Java library directories, knowing they're in a fixed path relative to the path from which java.
Improve this answer. Carl Smotricz Carl Smotricz The default Java7 wizard also installs java. This is not a legacy issue. Great answer anyway! If you update your Java version you may find you are still using the old version if it is in the PATH environment variable. You don't get a problem with them invoking an out-of-date version by default because of this copy. Try java -showversion instead of java -version. Very good and detailed answer, but missing the new best practice java introduces regarding path location switching.

Make sure you are not actually copying the files but creating soft links instead step 5. The same goes to the javapath and CurrentVersion directories steps 6 and 8. Good luck! Mia Thank you for taking the time to respond. I'll try it as soon as I get home. Otherwise, I'm doomed to use Java 8 :D. But it was for Android and it is now compatible so no big deal actually. It does not work if I am trying to switch java version build within the same 1.
