Map to string

     

import java.util.Iterator;
import java.util.Map;
import java.util.Set;

public class Util{

    public static String dump(Map map)
    {
        if (map == null)
            return "null";

        StringBuffer buf = new StringBuffer().append('{');
        Set keys = map.keySet();
        Iterator iterator = keys.iterator();
        Object key;
        Object value;

        boolean first = true;
        while (iterator.hasNext())
        {
            if (first)
                first = false;
            else
                buf.append(',');
            key = iterator.next();
            value = map.get(key);
            buf.append( key + "->" + value );
        }
        buf.append('}');
        return buf.toString();
