Programming questions like reversing String using recursion or How to find if Array contains duplicates are some popular examples of programming question in Java. These programming interview questions are from my personal collections and I have only chosen those which are not very difficult, can be solved easily but at the same time can become too complex or confusing, present lots of follow-up questions and test fundamentals of programming, OOPS and design.
I have not given answers to these programming questions but those can be found by Google and I will try to post links of answers here sometime later but at the same time, I will try to provide quick tips or hints on some questions.
Anyone who is following programming questions must be familiar with these questions and also knows the answer for most of these but for new guys and even for intermediate it's worth refreshing it before going to any programming job interview e.
String Programming Interview Questions The string is a primary and probably most common thing you come across on any programming language and so is with any programming interview. There is almost always a question on String whether its related to length or replace but I have always found one or two String programming questions on interviews.
This can be done by using either StringBuffer reverse method or by technique demonstrated in the solution here. Also, StringBuilder is not synchronized like StringBuffer and that's why faster and should be used for temporary String manipulation.
Couple of reasons which I think make sense is an implementation of String pool, Security, and Performance. Java designers know that String will be used heavily in every single Java program, so they optimized it from the start.
You can even use a regular expression to split a big string into several smaller strings. If you can solve all these String questions without any help then you are in good shape. If you need more practice, here is another list of 20 string coding questions.
Programming questions on Array An array is one of the topics where most of the programming questions are asked. There are many and many programming questions on Array and here I have included only some of them which are not very difficult to solve but some of array programming question can be extremely challenging, so well prepare this topic.
Here is a quick tip to solve this programming question: If you need more advanced questions based upon array then you can see also see The Coding Interview Bootcamp: And, if you feel 10 is not enough questions and you need more practice, then you can also check out this list of 30 array questions.
It actually compliments array and whatever you cannot do with an array, you can do with a linked list.
For example, the array needs contiguous memory to store objects but the linked list doesn't need that. It's difficult to add and remove elements in an array because you need to shift existing elements but that is very easy with a linked list, as you just need to change the pointer to accommodate them.
