Java Update

As pointed out several times throughout my guides, Java it is still essential for the operation of several programs. You can't do without it even for certain PC games or if you want to develop an application for Android smartphones and tablets. However, it must be handled with extreme care and, above all, it must be updated constantly.

The problem is that Java, given its enormous diffusion on a global scale and its compatibility with all software platforms (Windows, macOS, Linux, etc.), is often used by cybercriminals to carry attacks on computers. Updating it to the latest version available is the only solution to sleep relatively peacefully (the best solution, in reality, would be to uninstall it and not use it at all but, as mentioned, this is not always possible).

With today's guide, we will see, therefore, how to carry out theJava update on Windows and macOS, how to set the automatic download of the latest versions of the software and - equally important - how to remove all the obsolete versions of the same that may have been installed in the past on your computer: these are extremely simple operations to complete, do not fear!

Then click on thejava icon present in the search results.

In the window of the Java control panel which at this point is shown on the screen, select the tab Update. Then click on the button Update now located below and wait for the software to check for new versions online. If there is no update available and, therefore, the version of Java in use on your PC is the latest, you will see the message The latest Java platform is already installed on this system: in this case, click on the button OK to close it.

If, on the other hand, an update is available, the setup will start automatically to install it on your computer.
