The first and second columns show the data type of the flag and its name

The fourth column shows the flag default/applied value,

The fifth one shows category.

":=" indicates that the flag was set to that value either by the user or by JVM optimization (The process of Ergonomics).

We can also include following other options :

-XX:+UnlockDiagnosticVMOptions

-XX:+UnlockExperimentalVMOptions

-XX:+UnlockInternalVMOptions

For example:

java -XX:+UnlockDiagnosticVMOptions -XX:+PrintFlagsFinal -version
