Java drip: Map and string conversion public methods __java

A simple map and string conversion method, a more practical section of Java code

1 convert map to a string like username ' Chenziwen^password ' 1234

/**
 * Method Name: transmaptostring
 * Incoming parameter: Map
 * return value: String shape such as username ' Chenziwen^password ' 1234 *
public static String transmaptostring (map map) {
  java.util.Map.Entry Entry;
  StringBuffer sb = new StringBuffer ();
  for (Iterator iterator = Map.entryset (). iterator (); Iterator.hasnext ();)
  {
    entry = (java.util.Map.Entry) Iterator.next ();
      Sb.append (Entry.getkey (). toString ()). Append ("'). Append (Null==entry.getvalue ()?" ":
      Entry.getvalue (). ToString ()). Append (Iterator.hasnext ()? "^" : "");
  }
  return sb.tostring ();
}

2 Convert a string shape such as username ' Chenziwen^password ' 1234 into a map

/** * Method Name: Transstringtomap * Incoming parameter: mapstring shape such as username ' Chenziwen^password ' 1234 * return value: MAP * *
  public static Map Transstringtomap (String mapstring) {map map = new HashMap ();
  Java.util.StringTokenizer items; 
    for (StringTokenizer Entrys = new StringTokenizer (mapstring, "^"); Entrys.hasmoretokens (); Map.put (Items.nexttoken (), Items.hasmoretokens ()?
  (Object) (Items.nexttoken ()): null) items = new StringTokenizer (Entrys.nexttoken (), "'");
return map; }
