How to print in a jtext as if it were a console?

I mean: 

for (int r = 0; r < 5; r++)
    sout(r+","); //jtext.setText(r + ",")
  

0,1,2,3,4,

since in the jtext it would print only the last 4,

you can do it in the following way:

  • Define a String where you will store the text
  • You use your cycle to concatenate the numbers
  • Finally you put the resulting chain in your JTextField (I guess it's what you use)

    • It would be like this: 

    String cad = "";
for(int i = 1; i <= 4; i++)
    cad += i + ", ";
jtext.setText(cad); // cad = "1, 2, 3, 4, "

    I hope you serve, greetings.
