  1. CSC1200 INTRODUCTION TO PROGRAMMING Dr. Maureen Markel http:faculty.msmc.edu

  2. Chapter 1: Introduction Object-Oriented Program Development Using Java: A Class-Centered Approach

  3. Objectives of Chapter 1 • Computer Science and Programming Languages • Objects and Classes • Constructing a Java Program • The PrintStream Class’s print() and println() Methods • Using the javax.swing Package • Programming Style • Common Programming Errors

  4. Computer Science and Programming Languages • Information age • Almost totally dependent and driven by information technology • Computer science • Science of computers and computing • Computer scientists • Solve problems using the scientific method

  5. Fundamental Areas of Computer Science This text will focus on: • An introduction to computer architecture • The Java programming language • Class development and design • Algorithm development

  6. Programming Languages • Computer program • Also called software • A self-contained set of instructions and data used to operate a computer to produce specific results • Programming • process of developing and writing a program • A programming language • is a set of instructions that can be used to construct a program

  7. Programming Languages (continued) • Low-level languages: • Machine language • Assembly language

  8. Programming Languages (continued) • High-level languages: • Use instructions that resemble natural languages • Can be run on a variety of computer types • Examples: • Pascal • Visual Basic • C • C++ • Java

  9. Programming Languages (continued) • Source program • Programs written in a computer language • Interpreted language • Each statement is translated individually and executed immediately upon translation • Compiled language • All statements are translated as a complete unit before any one statement is executed

  10. Programming Languages (continued) • Java is both: • Compiled • Interpreted • Java Virtual Machine • Software program that can read bytecode produced by the compiler and execute it

  11. Procedure and Object Orientations • Procedure-oriented language • Available instructions are used to create self-contained units • Object-oriented language • Program must first define objects it will be manipulating • Java is object-oriented

  12. The Development of Java • History: • Fortran • COBOL • BASIC • Pascal • C++ • Java

  13. The Development of Java (continued) • Web browser • A program located and run on a user’s computer to display Web pages • Java can run from a Web browser • Java provides: • Cross-platform compatibility • Write-once-run-anywhere capability

  14. Objects and Classes • Objects • Part of the Java programming language as component types • Can be custom tailored by programmers • Programmers can define custom objects

  15. A Class Is a Plan • The structure for a class of objects must be created at the start of the programming process • Class • Explicitly written plan • Complete set of parts and instructions needed to create items

  16. From Recipe to Class • Data declaration section • Description of data to be used • Methods section • Defines how to combine data components to produce desired result

  17. Task: Explain the following terms • High level language • Source Code • Interpreted language • Compiled language • Characteristics of three different programming languages excluding Java • Host computer • Procedural language • Object-oriented language • Advantages of Java
