The put() method of HashMap works in the principle of hashing. It is responsible for storing an object into backend array. The hashcode() method is used in conjunction with a hash function to find the correct location for the object into the bucket. If a collision occurs then the entry object which contains both key and value is added to a linked list and that linked list is stored into the bucket location

  1. This is a answer 1-As a core Java developer, you probably already realize you need to demonstrate a high level of technical proficiency. However, you should also understand that employers like to see applicants who possess soft skills as well. Communication, listening, and cooperation all rank among important skills that all professionals need to utilize their technical knowledge effectively. Because developers may have a reputation for prizing knowledge over the ability to work with others, you need to show employers that you understand and value soft skills. In our core Java developer resume sample, the applicant’s skill section includes mostly technical abilities but also mentions multitasking and being a team player. His work experience section supports these claims by referring to successful cross-functional collaboration.
