Can a Joption Pane be made to wrap around after its width exceeds a certain value

You can use the \n character literal for a line break.

Concatenate a string from your data input.

you can write it to a hidden label and use the FontMetrics class to get the width, to which you can use to determine where to insert a line break.

Personally I would set a maximum character length per line and insert the newlines on the first space character previous to that length.

I agree w/KYA. Read in your data as a String, convert it to a StringTokenizer, and then feed the individual tokens into your JOptionPane. If the approximate length of each token is the same, then you can simply add a carriage return on an interval.

Convert your string into a char[] array then after a certain number of character replace the first ' ' by a '\n' and start again

CODE

int maxByLine = 60;
char[] digit = line.toCharArray();
int count = 0;
for(int i = 0; i < digit.length; i++) {
    count++;
    if(count > maxByLine) {
       if(digit[i] == ' ') {
          digit[i] = '\n';
          count = 0;
       }
    }
}
line = new String(digit);
