INTRODUCTION TO DATA STRUCTURES
Data Structure is a way to store organized data in a computer. Data Structure is a set of data elements with certain logical relations, applies specific storage structures in a computer, and encapsulate corresponding operations. Thus, it contains three aspects: logical relations, storage relations, and functions. Different kinds of data structures are suitable for other applications, and some are even specialized for specific job tasks. For example, computer networks rely on routing tables to operate, and B-tree height is suitable for database encapsulation.
INTRODUCTION TO THE JAVA LANGUAGE
Java is an object-oriented programming language. It does absorb the advantages of the C++ programming language and abandon C++ complexity like multiple inheritance Pointers and other concepts. Therefore, Java has two features of practical and easy use. First, as a representative of static object-oriented programming languages, the language implements object-oriented theory very well. It allows programmers to do complex programming in an elegant way of thinking.
