How can a skip list class be implemented in Java?
To implement a skip list class in Java with the specified methods and functionality, follow these steps: create a class named 'SkipList' in a file named 'skipList.java', define the necessary instance variables and methods, implement the 'skipInsert(k,v)', 'skipRemove(k)', and 'skipSearch(k)' methods, and include a main method that creates a skip list from a hardcoded sequence of 10 integers and prints out the resulting list to stdout.
Creating SkipList Class
In order to implement a skip list class in Java, you need to create a new class named 'SkipList'. This class will serve as the blueprint for your skip list implementation.
Defining Instance Variables and Methods
Within the SkipList class, define the necessary instance variables and methods required for the skip list implementation. These variables and methods will be used to manage the nodes in the skip list and perform operations such as insertion, removal, and search.
Implementing skipInsert(k,v) Method
The skipInsert(k,v) method is used to insert an entry with key 'k' and value 'v' into the skip list. This method should promote nodes to higher levels based on randomization. Implement the logic for inserting a new entry into the skip list.
Implementing skipRemove(k) Method
The skipRemove(k) method is responsible for removing the position corresponding to key 'k' from all levels in the skip list. This method should handle the deletion of a node with the specified key from all levels of the skip list structure.
Implementing skipSearch(k) Method
The skipSearch(k) method is used to search for key 'k' in the skip list. This method should return the position corresponding to key 'k' in the bottom list, or null if the key is not found in the skip list.
Including Main Method
Include a main method in the 'skipList.java' file that creates a skip list from a hardcoded sequence of 10 integers and prints out the resulting list to stdout. This main method will serve as the entry point to your skip list implementation and demonstrate its functionality.
By following these steps, you will be able to successfully implement a skip list class in Java with the specified methods and functionality. Be sure to test your implementation thoroughly to ensure it works as intended.
