This article mainly introduces how to use YUM to install JDK under Linux, which has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

JDK is the abbreviation of Java Development Kit (Java Development Kit). Literally translated is the tool developed by java.
