I have the following requirement:
I have a JTree placed within a JScrollPane. The model of the JTree is
now updated every other second. But the additional entries are added
at the top of the Model (index is nearly always 0).

Hi there, I know this problem has propped up all over the place but
the answers have not helped me to solve my problem entirely. I think
this is because with each change of data in any cell in my table, the
entire table needs to be reinitialised - that is, the data model is

I was looking through some old pascal line printer listings from
<mumble mumble> decades ago, and thought I'd try to recreate an old
game I wrote in Java.  Java, of course, doesn't do WRITELN and READLN
