java properties files, using a key as another keys value, is this possible -

i know if there way use key key's value in .properties files.

for example possible, or there other way achieve similar this?

key = another_key  app.name=stack on flow   app.title.welcome=welcome {app.name}

so when value of app.title.welcome should "welcome stack on flow"

the apache commons configuration project has implementation capable of doing variable interpolation.

read section named variable interpolation

application.name = killer app application.version = 1.6.2 application.title = ${application.name} ${application.version}

you need third-party library in class path, on other hand not have worry writing yet implementation :)

you might read properties how to well.
