java - reading a hashtable from a text file -

i have 2 files - write.java , read.java. write.java file writes hashtable text file , function of read.java read hashtable text file.

write.java:

hashtable hash1 = new hashtable(); hash1.put("1", "hi!");  filewriter filewriter = new filewriter("abc.txt"); bufferedwriter bufferedwriter = new bufferedwriter(filewriter); bufferedwriter.write(hash1.tostring()); bufferedwriter.close(); 

it writes peroperly text file. read.java has read hashtable abc.txt , add 1 more key value paid. best way achieve this?

read.java:

string dnstemp = "abc.txt"; filereader filereader = new filereader(dnstemp); bufferedreader bufferedreader = new bufferedreader(filereader); string line = bufferedreader.readline(); bufferedreader.close(); 

but line variable string...how convert hashtable perform further operations?

use properties instead hashtable. has capability of loading , storing
