Gum and tooth next to extraction site sore. The tooth next to the 1st lower molar I had removed 12 days ago has felt a bit strange for about a week or so now, I felt around it & the gum beneath it & the gum felt softer than normal.
The first thing you need to do after installing the JDK is creating an environment variable named JAVA_HOME and then update the PATH variable. 1  JAVA_HOME: stores location of the JDKâs installation directory. When you install development tools, they will first check for the JAVA_HOME variable.
Environment Variables. Many operating systems use environment variables to pass configuration information to applications. Like properties in the Java platform, environment variables are key/value pairs, where both the key and the value are strings. The conventions for setting and using environment variables vary between operating systems, and also between command line interpreters.
