Java exceptions are library types and language features used to represent and deal with program failure. If you’ve wanted to understand how failure is represented in source code, you’ve come to the right place. In addition to an overview of Java exceptions, I’ll get you started with Java’s language features for throwing objects, trying code that may fail, catching thrown objects, and cleaning up your Java code after an exception has been thrown.

In the first half of this tutorial you’ll learn about basic language features and library types that have been around since Java 1.0. In the second half, you’ll discover advanced capabilities introduced in more recent Java versions.

In Datastructures and algorithms in Java, Part 2 I introduced a variety of techniques for searching and sorting one-dimensional arrays, which are the simplest arrays. In this article we’ll explore multidimensional arrays. I’ll introduce the three techniques for creating multidimensional arrays, then show you how to use the Matrix Multiplication algorithm to multiply elements in a two-dimensional array. I’ll also introduce ragged arrays and show you why they are popular for big data applications. Finally, I will answer the question of whether an array is or is not a Java object.
