How to read ini file using Java

Java Code:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.HashMap;
import java.util.Properties;

public class iniReader {
    protected HashMap<String, Properties> sections = new HashMap<String, Properties>();
    private transient String currentSecion;
    private transient Properties current;

    public IniReader(String filename) throws IOException {
        BufferedReader reader = new BufferedReader(new FileReader(filename));
        read(reader);
        reader.close();
    }

    protected void read(BufferedReader reader) throws IOException {
        String line;
        while ((line = reader.readLine()) != null)
        {
            parseLine(line);
        }
    }

    protected void parseLine(String line) {
        line = line.trim();
        if (line.matches("\\[.*\\]")) 
        {
            currentSecion = line.replaceFirst("\\[(.*)\\]", "$1");
            current = new Properties();
            sections.put(currentSecion, current);
        } else 
        if (line.matches(".*=.*")) 
        {
            if (current != null) 
            {
                int i = line.indexOf('=');
                String name = line.substring(0, i);
                String value = line.substring(i + 1);
                current.setProperty(name, value);
            }
        }
    }

    public String getValue(String section, String name) {
        Properties p = (Properties) sections.get(section);

        if (p == null) 
        {
            return null;
        }

        String value = p.getProperty(name);
        return value;
    }
}
