The document provides an overview of a course on Java and data structures. It discusses Java's history and origins as an object-oriented language influenced by C and C++. It then outlines the course syllabus which covers core Java concepts, object-oriented principles, exceptions, I/O streams, and various data structures like arrays, stacks, queues, linked lists, trees, graphs and their algorithms. The document concludes with discussing tools like JDK needed for the course and recommended textbooks.

- 2. Introduction • Java is a object-oriented programming language. • Related to C++, which is an offspring of C-Language. • Much of the characteristics of Java inherited from C-Language & C++. Nilesh Dalvi, Lecturer@Patkar-Varde College, Goregaon(W). C-Language C++ Java Syntax Oops features
- 3. History of Java • General purpose object-oriented language developed by sun microsystems in 1991. • It is initially called ‘oak’, was renamed as ‘Java’ in 1995. • Originally designed to develop software for consumers electronic devices like toasters, TVs, etc. • First language that is not tied to any particular H/W or OS • Java is platform-neutral language.
