7.1 Introduction
This chapter introduces data structures—collections of related data items. Array objects are data structures consisting of related data items of the same type. Arrays make it convenient to process related groups of values. Arrays remain the same length once they’re created. We study data structures in depth in Chapters 16–21.
After discussing how arrays are declared, created and initialized, we present practical examples that demonstrate common array manipulations. We introduce Java’s exception-handling mechanism and use it to allow a program to continue executing when it attempts to access an array element that does not exist. We also present a case study that examines how arrays can help simulate the shuffling and dealing ...
