- Q3. What is the internal working of HashMap in java?
- Ans.
HashMap in Java is a data structure that stores key-value pairs and uses hashing to efficiently retrieve values.
HashMap uses an array of linked lists to store key-value pairs.
When a key-value pair is added, the key is hashed to determine its index in the array.
If multiple keys hash to the same index, a linked list is used to handle collisions.
HashMap allows null keys and values, and does not guarantee the order of key-
- Q4. What happens if I have a key with a null value in HashMap and where it will get stored?
- Ans.
A key with a null value in HashMap will be stored in the HashMap as a key-value pair with a null value.
In a HashMap, keys can have null values but only one key with a null value is allowed.
If you try to store a key with a null value multiple times, the previous value associated with that key will be overwritten.
Example: HashMap
- Q5. Difference between fail-fast and fail-safe? which one is synchronized?
- Ans.
Fail-fast stops immediately upon detecting an error, while fail-safe continues to operate despite errors. Fail-safe is synchronized.
Fail-fast immediately stops the operation upon encountering an error, ensuring that no further damage is done.
Fail-safe continues to operate despite errors, often by handling the error and allowing the program to continue running.
Fail-safe is synchronized, meaning that it is designed to ha...
- Q6. HashMap vs LinkedHashMap?
- Ans.
HashMap is unordered while LinkedHashMap maintains insertion order.
HashMap does not maintain insertion order while LinkedHashMap does.
LinkedHashMap extends HashMap and adds a doubly-linked list to maintain order.
HashMap is faster for iteration while LinkedHashMap is slower due to maintaining order.
- Q7. Load factor in HashMap?
- Ans.
Load factor in HashMap determines when the HashMap should be resized to maintain performance.
Load factor is a measure of how full the HashMap is allowed to get before its capacity is automatically increased.
The default load factor of HashMap is 0.75, which means the HashMap will be resized when it is 75% full.
Increasing the load factor reduces the space overhead but increases the time cost of resolving collisions.
Examp...
