   pstree shows running processes as a tree. The tree is rooted at either pid or init
   if pid is omitted. If a user name is specified, all process trees rooted  at  pro-
   cesses owned by that user are shown.

   pstree  visually  merges identical branches by putting them in square brackets and
   prefixing them with the repetition count, e.g.

       init-+-getty
            |-getty
            |-getty
            ‘-getty

   becomes

       init---4*[getty]

   Child threads of a process are found under the parent process and are  shown  with
   the process name in curly braces, e.g.

       icecast2---13*[{icecast2}]

man pstree:

            |-getty
            |-getty

따라서 프로세스 15스레드 java.
