Thread: Hash Functions

Hi

Do you guys know about Hash functions?

Is there a library for this?

Thanks a lot

Hash functions is a very general term. What exactly do you need? A typical hash function uses multiplcation, addition, with a prime number in there somewhere to generate the hash. For example, a simple hash function for a class containing two values would be

public class Test{
	int var1;
	int var2;
 
	 @Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + var1;
		result = prime * result + var2;
		return result;
	}
}

Eclipse can generate these for you.

Hello i just stumbled upon this thread and i think that my library can help you. You can find its thread at http://www.javaprogrammingforums.com...ndcentral.html and its project at http://code.google.com/p/grandcentral/
