This article will explain in detail about the failure of installing jdk in Linux. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Sometimes out of necessity (such as installing the latest eclipse), we need to install a specified version of JDK. However, after the installation is complete, retype the command to query the JDK version only to find that the version number has not been updated.

1. Under the Linux system, start the terminal. Type the command su in the terminal and enter. Then type the root password (note that the password is not displayed on the screen), press enter, and log in to the root account.

2. Type the command java-version to query the current JDK version.

3. If the version number is not desired, type rpm-qa | grep gcj.

4. Type the command yum-y remove (followed by the version obtained by the query) to remove the old version.

This is the end of this article on "what to do if you failed to install jdk in Linux". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
