JAVA 8 handles collisions using separate chaining and open addressing.

• Separate chaining uses linked lists to store multiple values at the same index in the hash table.

• Open addressing uses a probing sequence to find the next available slot in the hash table.

• JAVA 8 also introduced the ConcurrentHashMap class which uses a combination of both techniques for better performance.

• Example: HashMap map = new HashMap<>(); map.put("key", 1);

• If a collision occurs, the new value will be ad...read more
