I may
be missing something here, but what the hey...
Wouldn't it be easier (and likely very efficient, if not optimal) to use
java.swing.text.Segment and java.swing.text.Utilities.getBreakLocation()
?

Subject: [jdjlist] RE: String segmentation??? (was: RE: Slow: string += s tring)I have to test this, but I think substring is probably adequate for most purposes. The other way to go would be to is to use a char array, as below. I don't know which one is faster -- my hunch is it depends on the size and number of String objects created.char[] c = myString.toCharArray();int paragraphLength = 35;int fullArrayLength = c.length;Vector splitStrings = new Vector(fullArrayLength/paragraphLength + 1);StringBuffer splitString = null;for(int j = 0; j < fullArrayLength/paragraphLength; j++) {splitString = new StringBuffer();for(int i = 0; i < paragraphLength; i++) {splitString.append(c[j*paragraphLength + i]);}splitStrings.addElement(splitString.toString());}You guys might want to test this one if you want to use it -- I may have some off by 1 errors or something...Greg____________________________________________________-----Original Message-----

Subject: [jdjlist] String segmentation??? (was: RE: Slow: string += string)While we are talking about string concatenation, what about truncation? Is there a more efficient way to break a long string into segments than using substring()? For example, if I read a paragraph into a string and then wants to break it into line depending on the size of dialog box that will display the paragraph. What is the most efficient way of doing that?Thanks in advancePatrick Li____________________________________________________
