Java SE (Java Platform, Standard Edition)

Could you help me with my text adventure.I am looking to display the welcome message and ask the user their name only.
When the user has entered their name I would then like to display the next set of text in my adventure game which
is enter a number below and scroll with it.Then when the user has entered their number I would like to display the next paragraph,then get user input,then display the next paragraph,text adventure style.
The questions are that I am unable to get the text of the game to display in sequences,as it is displaying all in 1 go at the moment.The scrollbar works but only manually.When I try to set the input number variable as getint this is underlined in red but gettext isnt.The progress bar is for a health bar but is in its early stages yet.My main concern is displaying the text in blocks from following user input.If anyone could help me with this and keeping the code as simple as possible I would appreciate it as Ive been stuck for a while with this problem.
Many thanks
simsy
