Hello everybody
I wrote this program a few months back when I wan learning JAVA.I haven't learned java yet though because its to vast.
The program is console based. It uses the util package of java in a great way. It keeps record in a flat file. You should create a Data file called phone.dat in same folder where phone.java is kept.
So here is the code:-(phone.java)
CODE

import java .io .*;
import java .util .*;
import java.awt.event.*;



public class phone
{
    public void new_record()
    {
       String id,name,city,add,number,total,list;
         boolean bln=false;
              try
        {
          Properties pr=new Properties();
          FileInputStream fin=new FileInputStream("phone.dat");
           if(fin!=null)
             {
             pr.load(fin);
             }    
            BufferedReader br1=new BufferedReader (new InputStreamReader(System.in));
              FileOutputStream fout=new  FileOutputStream("phone.dat");
                  for(;;)
                   {
                     System.out .println("Enter the 'ID', 'q' for quit:");
               id=br1.readLine().toUpperCase();
                     bln=pr.containsKey(id);
                      System.out .println("FLag"+bln);
                     if(bln)
                      {
                       System.out.println("ID id already exists, Please Enter another ID:");
                       continue;
                      }
                    if((id.toUpperCase()).equals("Q"))
                    break;
                    System.out.println("enter name:");
              name=br1.readLine().toUpperCase();
              System.out.println("enter Phone number:");
              number=br1.readLine().toUpperCase();
