These commands are not valid because they are not structured properly. Instead of typing multiple lines in a single command, they should be separated into individual commands. Also, the first command is missing the word "java" after "openjdk". Here are the corrected commands:

1. To check the version of OpenJDK installed:

java -version

2. The output of the above command will display the version of OpenJDK installed on the system.

Note: The second and third lines in the original commands are not valid commands and should not be entered.
