Sorry friends for the delay in reply.
Hi naraharirao mocherla
, Don't worry much for the hashCode() method and collections. In collections you only do need to know the purpose of various collection interfaces, difference between their implementing classes like arraylist and vector implement the additional RandomAccess interface which means they can be accessed randomly. Just cram the access order, insertion/deletion order and the performance issue between implementing classes of same interface i.e. which one inserts faster, which one accesses elements faster and why ? , and in hashtable based implemention in Sets and Maps try to memeorise the default initialcapacity and loadfactor with different constructors.
I got one question wherein i need to type in the output of some string
operation mentioned int he program and rest were objective type.
In hashcode just remember the general contract(3 points) of hashcode method and then solve a number of questions on this topic until all your doubts are erased out. Continue posting your doubts so that me or someone knowing the answer and reason can help you.
All the best for your preparation and exam.
