have a employee class to store all employee related values in it.
Since u plan a search on the employee number,
Use java.util.Hashtable and use the employee number as the key there with employee class instance as the value.
So u need to wrap the key in Integer class though (java problem :-(, removed in C# though!).
class Employee{
String name;
String address;
int empNo;
}
Hashtable h = new Hashtable();
h.put(new Integer(empNo),
new Employee(//supply name/address to constrctor));
h.put(new Integer(empNo),
new Employee(//supply name/address to constrctor));
//repeat.
Now h.get(empNo) w'd get u the details corresponding to that employee.
karthik.
