Hi ,

why are u not able to append???

Use Hashtable's put() methods which will take key value pair.

Use Hashtable get() method to get data.

See your jdkhome\src\java\util\Hashtable.java for api's.

Hashtable as database:

1.Create a class which represent your table.employee as empid,name,salary

Eg: public class Employee {
   public int empId;
   public Stirng name;
   public double salary;

Assme that empId is primary key.

Create a object of Employee.

Employee emp = new Employee();
emp.empId = 1;

Hashtable records = new Hashtable();
// Key and value pair

// In some where you can get data as
int empId = 1;
Employee emp = (Employee) records.get(empId);//giving key and getting value

System.out.println("Emp salaey:"+emp.salary);

Best of luck.
