Chapter 10: Arrays and Strings

This chapter covers a wide range of problems involving strings and arrays. Since Java strings and arrays are common topics for developers, I will briefly introduce them via several headlines that you must remember. However, if you need to deep dive into this topic, then consider the official Java documentation (https://docs.oracle.com/javase/tutorial/java/).

By the end of this chapter, you should be able to tackle any problem involving Java strings and/or arrays. It is highly likely that they will show up in a technical interview. So, the topics that will be covered in this chapter are pretty short and clear:

• Arrays and strings in a nutshell
• Coding challenges

Let's start with a quick recap of strings and arrays.
