How do you list a string that has been internalized in jvm?

Java - tell me if String is interned?

I would like to have a list of lines that jvm has learned, either because they are literal, because the intern method is what they were called. How can I generate it?

You can get the total size of all interned strings as:

$ jmap -permstat 543

How can I create it?

You cannot run the program. An API for repeating the pool of inner rows does not exist.

You could in theory do this using a debug agent. This will include:

  • , String .
  • , str == str.intern().
