What are hash functions in Java and how do they work?
Hash functions in Java are algorithms that transform input data into a fixed-size string of characters, which is typically a hash code. They are commonly used in data structures like hash tables to quickly locate a data record.

Sure! A common example is the hashCode() method in the String class. It generates a hash code for a string based on its characters.
How do I implement a custom hash function?
To implement a custom hash function, you can override the hashCode() method in your class. Ensure it returns an integer based on the object's attributes.
What are some common use cases for hash functions?
