making the message wrap in a JDialog

[Randall Twede]

i have the following code which works ok except the message doesn't wrap, so the JDialog(the lucky recipient of the return value from getMessage()), is one long...long...long..line

import java.util.ArrayList;
import java.math.BigInteger;

class Euler8 implements Problem
{
	String string = ("" + "73167176531330624919225119674426574742355349194934" +

	public String solve()
	{
		ArrayList list = new ArrayList();
		int answer = 0;
		return string;
	}
	
	public String getMessage()
	{
		return "Find the greatest product of five consecutive digits in the 1000-digit number." + string;
	}
}

can i perhaps set the width of the JDialog?

[Michael Dunn]

set it as the text of a JTextArea (in scrollPane) with lineWrap set to true

[Randall Twede]

it is one of several classes that implement the same interface. the main program treats them all the same using a JDialog to display the message

i suppose i could add some newline characters, but after what i had to do to turn it into a string in the first place

[Randall Twede]

well it's ugly but it works

	public String getMessage()
	{
		String message = ("" + "73167176531330624919225119674426574742355349194934" + "\n" +

[Michael Dunn]

I still think it's simpler with a textArea.
Run this to see what it looks like.
