How do I do a partial word search?

[hrin kuek]

Hi all,

I have a customer's name as an attribute of a reservation object stored in my vector of reservation objects. My current search only does an exact match of a customer name. How do I do a partial word search eg. if my customer name is danielle and I only key in dan, how do i get it to return danielle?

Hope to hear from someone soon! Thank you!

public void searchcustName(String custName, Vector v)
{
for( int i = 0; i < v.size(); i++)
{
Reservation aReservation = ((Reservation) v.elementAt(i));
if ((aReservation.getcustName().equals(custName)))
{
System.out.println();
System.out.println("Booking Id: "+ i );
System.out.println("Customer Name: " + aReservation.getcustName());
System.out.println("Customer Contact No: " + Reservation.getcustNo());
System.out.println("Number of covers: " + aReservation.getCovers());
System.out.println("Smoking: " + aReservation.getSmoking());
System.out.println("Date of reservation: " + aReservation.getDate());
System.out.println("Reservation Start Time: " + Reservation.getstartTime());
System.out.println("Reservation End Time: " + aReservation.getendTime());
System.out.println("Comments: " + aReservation.getComments());
System.out.println("Table id: " + aReservation.getTableid());
System.out.println();
searchCount++;
}
}
if (searchCount==0) System.out.println("The record of "+custName+" cannot be found!");
else System.out.println("Number of records found: "+searchCount);
}

Just using String methods, try haystack.indexOf(needle) to see if a small string is included in a large one.

The Pattern reference given above is all about regular expressions. RegEx is great fun and can do very powerful pattern matching. It looks scary but is fairly easy to pick up by copying examples. Try this Sun Tutorial or google for others to get started.

Stan's suggestion is good. indexOf() will suffice for your case ( and for many other cases).

If you're still keen in using regular expression from the link that I'd posted, you could use it with String's match() method.

After reading Stan's suggestion, I think you should just use indexOf() to keep things simple.
