Thread: I want to improve my code.

Hello, I wrote a program to extract table data from HTML document.
However I want to shrink this code more because it has to use large array variables.
Could you give me any advice for improving this code more?

import java.util.regex.Matcher;
import java.util.regex.Pattern;
 
// This program copies all of table data 
//   in a HTML document into the array of String type.
class Tblextrct {
        enum STATE {cnct, dntct};
 
    	public Tblextrct(){		
        }
 
    	public String [][] tableAnalysis(String ss, boolean debug){
 
            Pattern trs  = Pattern.compile("^<tr");
            Matcher trsm;
            Pattern tre  = Pattern.compile("^</tr>");
            Matcher trem;
            Pattern tds  = Pattern.compile("^<td");
            Matcher tdsm;
            Pattern tde  = Pattern.compile("^</td>");
            Matcher tdem;
            Pattern tags = Pattern.compile("^<(table|/table|tr|/tr|td|/td)");
            Matcher tagm ;
            Pattern ntag = Pattern.compile("^[^<]");
            Matcher ntagm ;
            Pattern spc = Pattern.compile("^(\\s+)$");
            Matcher spcm ;

One suggestion would be to use variable names with some meaning.
array does not say anything about what it contains or how it is used and you can tell it is an array by the syntax.

Also Using program Comments helps people understand what the code is supposed to do.
