To check the current version of JDK installed on a Linux system, you can use the following method:

  1. Use the command java -version: Open the terminal and type the following command:
  2. What is the version of Java installed on this system?
  3. This will display information about the version of Java Runtime Environment (JRE) currently installed on the system.
  4. To check the version of Java Development Kit (JDK) installed on your system, use the command “javac -version”.
  5. What is the version of Java compiler installed on this system?
  6. This will display the version information of the Java compiler installed on the current system.
  7. Check the JAVA_HOME environment variable: Another way is to check the JAVA_HOME environment variable set in the system, which usually points to the installation directory of the JDK. You can view the value of the JAVA_HOME variable by using the following command.
  8. Print the value of JAVA_HOME.
  9. Then go into the directory to check the specific JDK version information.

You can use these methods to view the current JDK version information on a Linux system in order to confirm the Java version being used.
