In this chapter, we are going to learn some of the most important data structures in Java. We'll look at what arrays are and how they are useful when we need to work with sequences of variables. We'll write a program in NetBeans using arrays to understand how they work. This chapter will also walk us through the concept of multidimensional arrays. We'll write a program to create a chessboard using a two-dimensional array.
Next, this chapter will illustrate what ArrayLists are and how they provide increased functionality when compared to arrays. Finally, we'll look at the Map data structure and implement it in NetBeans.
More specifically, we'll cover the following topics:
- Arrays and their syntax
- An array example to print the English alphabet
- Multidimensional arrays
- A program to create a chessboard using a 2D array
- ArrayList and its example...
