Re: run length encoding question

Question

I have this string:
String s = "########## \r\n# #########\r\n";
I want to run length encode the results. I am successful at encoding it:
10#6-|#5-9#| // I am using a delimeter here: "|". I am also using the replace ('-') for whitespace
I need help with this: how to suppress the trailing whitespace if there is only whitespace before the delimeter. I want my output to be:
10#|#5-9#|
thanks for the help

Answer 1

Yes, I would like to generate code in the encoding phase. I need help in the construct of the conditional "IF" to say something like this in pseudo code: if there is ONLY whitespace between last character and the "|" delimeter, do not print to the console.
This is the method I am using for the encoding part:
public class LevelEncodeTrimTest1 {
public String encode(String input) {
StringBuffer dest = new StringBuffer();
for (int i = 0; i < input.length(); i++) {
int runLength = 1;
while( i+1 < input.length() && input.charAt(i) == input.charAt(i+1) ) {
runLength++;
i++;
if (runLength == 1) {
dest.append(input.charAt(i));
if (runLength == 2){
//dest.append(runLength);
dest.append(input.charAt(i));
dest.append(input.charAt(i));
if (runLength > 2) {
dest.append(runLength);
dest.append(input.charAt(i));
return dest.toString();
thanks for the help.
