I'm not familiar with swt programming. But I remember the way to redirect stdout is to set the output stream, as you did in calling System. SetErr, to a customized object that implements PrintStream.
This object's print method will know how to update the GUI.
The problem is that you are echoing infinitely to System.out. What you probably want to do is to store the old System. Out at the start of run(), and echo there rather than to the new System.
Out in your read loop.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
