How to create an editable command line prompt in Java? -

is possible create editable command line prompt in java?

at moment command line looks following:

scanner scanner = new scanner(system.in); system.out.format("enter new value, press return keeping old value [%s]:", oldvalue); string newvalue = scanner.next(); 

edit:

while should works under normal circumstances, have command line, populate old value , let me edit it , take new value on pressing return; an editable textfield console.

i have tried jline2 this:

consolereader reader = new consolereader; reader.putstring("2"); string input = reader.readline(); 

...but unfortunately, hides value 2 until press key "2" , deletes whole line on backspace... , because of poor documentation of jline2 on github, have no idea if possible?

you use external library that, e.g. https://github.com/jline/jline2/wiki/jline-2.x-wiki
