How to Display Output in Text Area in java

Question

I am trying to display my output in Jtext Area.

while ((line1 = br1.readLine()) != null) {
    txt_output.append(line1+"\n");
    System.out.println(line1);
}

It gives me output once all the process finished. What want to show output execution line by line instead of all together.

please help me.....

are you saying your console gets updated in the process and JTextArea not? — Oleg Mikheev

One similar post in Stackoverflow, deals with concurrency using threads.

Refer this one: Dynamically refresh JTextArea as processing occurs?

You can possibly use the

textArea.setText();

method every time when you want the message to be printed. It automatically removes the previous text and writes the new one.

The following method is very bad practice but you can try it for now int temp = 0; while ((line1 = br1.readLine()) != null) { if(temp==0){ txt_output.append(line1+"\n"); temp = 1; } if(temp==1) { System.out.println(line1); temp = 0; } }

I know the following method is very bad practice but you can try it for now

int temp = 0;
while ((line1 = br1.readLine()) != null) {
if(temp==0){
   txt_output.append(line1+"\n");
   temp = 1;
 }
 if(temp==1) {
  System.out.println(line1);
temp = 0;
}
}
