Overview of this book

Java is one of the most sought-after programming languages in the job market, but cracking the coding interview in this challenging economy might not be easy. This comprehensive guide will help you to tackle various challenges faced in a coding job interview and avoid common interview mistakes, and will ultimately guide you toward landing your job as a Java developer. This book contains two crucial elements of coding interviews - a brief section that will take you through non-technical interview questions, while the more comprehensive part covers over 200 coding interview problems along with their hands-on solutions. This book will help you to develop skills in data structures and algorithms, which technical interviewers look for in a candidate, by solving various problems based on these topics covering a wide range of concepts such as arrays, strings, maps, linked lists, sorting, and searching. You'll find out how to approach a coding interview problem in a structured way that produces faster results. Toward the final chapters, you'll learn to solve tricky questions about concurrency, functional programming, and system scalability. By the end of this book, you'll have learned how to solve Java coding problems commonly used in interviews, and will have developed the confidence to secure your Java-centric dream job.

Coding challenges

In the following 29 coding challenges, we'll tackle a set of popular problems encountered in Java technical interviews done by medium to large companies (including Google, Amazon, Flipkart, Adobe, and Microsoft). Besides these 29 coding challenges (discussed in this book), you may like to check out the following non-exhaustive list of strings and arrays coding challenges that you can find in my other book, Java Coding Problems (https://www.amazon.com/gp/product/1789801419/), published by Packt as well:

  • Counting duplicate characters
  • Finding the first non-repeated character
  • Reversing letters and words
  • Checking whether a string contains only digits
  • Counting vowels and consonants
  • Counting the occurrences of a certain character
  • Removing white spaces from a string
  • Joining multiple strings with a delimiter
  • Checking whether a string is a palindrome
  • Removing duplicate characters
  • Removing a given character
