How can implement a perfect hashed data structure and their operations?

[Daron_1]

public class HashedClass{ 
 
int ticketNumber; // keyfield 
string purchaserName; 
 
Hashtable hashtable = new Hashtable(); 
 
insert(); 
 
fetch();
 
delete(); 
 
update();
 
} 

I started a pseudocode above, but I know it needs more work. Are there any resources that can help guide me to implementing my own java hashed perfect algorithm? I know that you have to use the direct hashed four basic operation for each four methods, right? But how can I do that based on pseudocode?

I guess Google is your friend here. Example.

You shoud look at the JavaDoc for Java's HashTable for essential information. The source code for that is also on the web, so you can see how it's implemented (if that helps).
Your 4 methods will need parameters - thinking about those will also help clrify things.
