- Q3. 3)Types of iterator in java
- Ans.
There are three types of iterators in Java: Iterator, ListIterator, and Enumeration.
Iterator is the most commonly used iterator, used to traverse collections like ArrayList, HashSet, etc.
ListIterator is used to traverse lists and allows bidirectional traversal and modification of elements.
Enumeration is the oldest type of iterator, used to traverse legacy collections like Vector and Hashtable.
- Q4. 4)How hashmap works internally
- Ans.
HashMap is an implementation of Map interface that stores key-value pairs using a hash table.
HashMap uses hashing to store and retrieve elements.
It uses an array of linked lists to handle collisions.
The hash code of the key is used to determine the index of the array.
If multiple keys have the same hash code, they are stored in the same linked list.
When retrieving a value, the hash code is used to find the correct linke

- Q8. 8)which java 8 features do you use in your current project
- Ans.
I use lambda expressions, streams, and default methods in my current project.
Lambda expressions: I use them to write more concise and functional code.
Streams: I use them for processing collections of data in a declarative way.
Default methods: I use them to provide default implementations in interfaces.
- Q9. 9)how to avoid hash collision
- Ans.
To avoid hash collisions, use a good hash function, increase the size of the hash table, and handle collisions using techniques like chaining or open addressing.
Use a good hash function that distributes the keys evenly across the hash table.
Increase the size of the hash table to reduce the chances of collisions.
Handle collisions using techniques like chaining (using linked lists) or open addressing (probing).
