using string buffer or tokenizer

Posted: Apr 21, 2003 9:50 PM

I have to write a program that reads a sentence in and check to see weather it has a balanced number of parenthesis. how would I do this, I know there is some way to take the spaces out of a sentence and iterate trough each character in a string. How do I use the string buffers and tokenizers?

U check the jdk1.4 api

u try this code may be u get some idea ...

import java.util.regex.*;

public class ReplaceAll {

public static void main(String args[]){

Pattern p = Pattern.compile("<a href");
StringBuffer buf = new StringBuffer("this is to test hyperlink <a href=http://www.k7mail.com>k7mail.com</a> just see the output and lets see what happens here it is <a href=http://www.k2mail.com> k2mail.com </a>");
Matcher m = p.matcher(buf.toString());
StringBuffer sb = new StringBuffer();
while(m.find()){

m.appendReplacement(sb,"<a target=_blank href");
}
m.appendTail(sb);
System.out.println("The output is "+sb.toString());

}

}
