- Q1. How hashmap works internally?
- Ans.
Hashmap is a data structure that stores key-value pairs and uses hashing to retrieve values quickly.
Hashmap uses a hash function to convert the key into an index in an array.
Collisions can occur when two keys map to the same index, which is resolved using separate chaining or open addressing.
Hashmap provides constant time complexity O(1) for insertion, deletion, and retrieval of values.
Java's Hashmap implementation use...
- Q2. Why string is immutable?
- Ans.
String is immutable to ensure thread safety and prevent unintended modification.
Immutable objects are safer to use in multi-threaded environments as they cannot be changed by other threads.
String pool is possible because of immutability, which saves memory and improves performance.
StringBuffer and StringBuilder classes are used for mutable string operations.
Example: String s = "hello"; s.concat(" world"); // returns a
Interview Preparation Tips
I have 4 years of experience in application development. At first, HR collect my details like notice period, salary expectations (which I mentioned 40% on current) etc.
After that HR scheduled my L1 round and I cleared L1 round with good feedback and rating.
After a week I called HR for scheduling L2 round but HR giving excuses like they don't have that much budget as per my expectations and they are rejecting my profile for further process.
I was trying to contact HR in many ways like, ph no, email, LinkedIn but no response from her.
I just wanted to say here, if you are preparing for Hexaware make sure you confirm your expectations and get it written from HR first then only proceed.
HR not only wasted candidate time but also play with candidate mentality. They forced you to resign from current company before giving any offer letter in the middle of interview process.
