hi guys, I was wondering if someone could help me write a search function that looks for a string in a hashtable. iv been struggling with this part of my assignment. iv done all the inserts parts and hash function itself.
thank you for replying. So the hash table implementation stores simple String data items, so we can only track if an item is in the data structure or not. The find function, determines if the string is in the data the hash table or not. The program loads the test dataset into the data structure, then performs find operations on all the test data items, followed by find operations on a disjoint set of unseen data items.
Iv been able to code the hash component, its just the search part that I'm not too sure of.
this is my hash function
publicint hash ( String s )
int sum = 0;
for(int=0, i<s.length(); i++)
return sum %size;
// return True if the hash table contains string s// return False if the hash table does not contain string s
my find function would resembles something along these lines.
boolean find ( String s )
boolean found = false;
int value = hashFunction(s, size);
As I suggested before, you just need a loop to compare your search value with all the ones already stored. If they are in an array or list then it is just a simple compare of each value. If they are in a database then it is a SQL SELECT statement.
That is the simple way and should work well for small lists. But there are plenty of Java classes that can manage lists and provide most of the functions that you would need. Check the documentation for things like List, Arrays etc.
Hi, I'm creating a custom IDE vased on the Netbeans platform. When I build my project, two launchers are created in the build\launcher\bin folder for Windows. I've to apply branding on them. Not on the custom IDE window, but on these two <application name>.exe and <application name>64.exe files. At least file properties like product version, file version, product name. I try to play with the branding\core\core.jar\org\netbeans\core\startup\Bundle.properties, but it affects only on the IDE window.
Is the a way to define these file properties?
Please help me on this VB.NET
assuming i have n=0(using a label to show how n is increasing) and i want my n to be increasing when a button is pressed till my n=100. E.g when button5 is pressed it should be n=n+5(initial n+5) or when button4 is pressed it should be n=n+4(initial n+4)
In addition to Peter's suggestion, we have already explained that if you want help then you need to show some effort on your part. You would also do well to make up your mind which language you want to work in. Switching between VB.NET and Java every few days is just a waste of your time, as you will be unlikely to get anywhere. Focus on one and go and study the language carefully. I have already given you the link (below) for the Java Tutorials, and you can find plenty of resources for VB.NET here on CodeProject and on MSDN.
