The similarity between these two operators assignment and equality may result in the accidental use of one in place of the other, and in many cases, the mistake does not produce an error message although some compilers produce warnings.
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.
Those two books have helped me a lot in the past and even today I read them whenever I need to refresh my concepts. String Programming Interview Questions String is the primary and probably most common thing you come across on any programming language and so is with any Computer programming questions on c interview.
There is almost always a question on String whether its related to length or replace but I have always find 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. Couple of reasons which I think make sense is implementation of String pool, Security, and Performance.
Java designers knows that String will be used heavily in every single Java program, so they optimized it from the start. You can even use regular expression to split a big string into several smaller strings. There are many and many programming questions on Array and here I have included only some of them which is 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: To answer this programming question I would say you start with simple solution on which you traverse the LinkedList until you find the tail of linked list where it points to null to find the length of linked list and then reiterating till middle.
After this answer interviewer will ask you find the middle element in single pass and there you can explain that by doing space-time trade-off you can use two pointers one incrementing one step at a time and other incrementing two step a time, so when first pointer reaches end of linked second pointer will point to the middle element.
How do you find the start of the loop? Programming questions on tree can become increasingly difficult when you think iterative but sometime can be very easy if you come with recursive solution.
Programming Questions on Searching and Sorting I have only included two programming questions related to searching and sorting but there are more can be finding on Google. Purpose of these programming questions is to see whether programmer is familiar with essential search and sort mechanism or not.
Both iterative and recursive? These programming questions are sometime based on problems faced by developer itself. I have not included many Software design related programming question which I have shared on Top 20 software design questions and answers ; you can also check that.
You can refer it to answer this question. Books to prepare for Programming Job Interviews There are lot of good books available, which can help programmer to do well on Interviews.
Here is a list of book, which I personally prefer, in the order, I like them.C Programming Tutorial in PDF - Learn ANSI, GNU and K/R standard of C programming language with simple and easy examples covering basic C, language basics, literals, data types, functions, loops, arrays, pointers, structures, input and output, memory management, pre-processors, directives etc.
