Interview Question : What are your strengths and weaknesses?

Interview process always include this question and it's a very important question from interviewer's perspective but it is more important for candidate too because this is the point where interviewer can decide whether he wants to go with the candidate or he might call the next candidate for the discussion.

Why we use String as key in Hashmap? or Is it good to have String as key in Hashmap?

String is one of the most used classes in any programming language. We know that String is immutable and final in java and java runtime maintains a String pool that makes it a special class. String is immutable, its hashcode is cached at the time of creation and it doesn’t need to be calculated again. This makes it a great candidate for key in a Map and it’s processing is fast than other HashMap key objects. This is why String is mostly used Object as HashMap keys. Note : HashMap uses hashCode() and equals() methods on keys for get and put operations. So HashMap key object should provide good implementation of these methods. This is the reason immutable classes are better suitable for keys,

HashMap<String, String> students = new HashMap<>();
students.put("S1", "Student1");
students.put("S2", "Student2"); students.put("S3&…

A Content Delivery Network (CDN) consists of two components: The Origin Server(s) – where the content to be distributed over Internet is originally stored & Cache Server(s) – where the content is duplicated. There is generally one Origin Server (either in the customer’s data center or in the cloud, with the content delivery network service provider – for example) and many cache servers (in multiple locations across the globe) so that, when a consumer is requesting a particular content on the Internet, it can be served by a cache server nearest to the consumer’s geographical location if the content is available there. Other wise, cache server fetches the content quickly from the origin server after protocol/…
