1 Lesson 01 Introduction MIT 12043, Fundamentals of Programming By: S. Sabraz Nawaz Lecturer in Management & IT M.Sc. In IS (SLIIT), PGD in IS (SLIIT), BBA (Hons.) Spl. in IS (SEUSL), MCP

2 Programs Computer programs, known as software, are instructions to the computer. You tell a computer what to do through programs. Without programs, a computer is an empty machine. Computers do not understand human languages, so you need to use computer languages to communicate with them. Programs are written using programming languages. MIT by S.Sabraz Nawaz 2

3 Programming Languages Machine Language Assembly Language High-Level Language Machine language is a set of primitive instructions built into every computer. The instructions are in the form of binary code, so you have to enter binary codes for various instructions. Programming with native machine language is a boring process. Moreover the programs are highly difficult to read and modify. For example, to add two numbers, you might write an instruction in binary like this: MIT by S.Sabraz Nawaz 3

4 Programming Languages Machine Language Assembly Language High-Level Language Assembly languages were developed to make programming easy. Since the computer cannot understand assembly language, however, a program called assembler is used to convert assembly language programs into machine code. For example, to add two numbers, you might write an instruction in assembly code like this: ADDF3 R1, R2, R3 MIT by S.Sabraz Nawaz 4

5 Programming Languages Machine Language Assembly Language High-Level Language The high-level languages are English-like and easy to learn and program. For example, the following is a high-level language statement that computes the area of a circle with radius 5: area = 5 * 5 * ; MIT by S.Sabraz Nawaz 5

6 Popular High-Level Languages COBOL (COmmon Business Oriented Language) FORTRAN (FORmula TRANslation) BASIC (Beginner All-purpose Symbolic Instructional Code) Pascal (named for Blaise Pascal) Ada (named for Ada Lovelace) C (whose developer designed B first) Visual Basic (Basic-like visual language developed by Microsoft) Delphi (Pascal-like visual language developed by Borland) C++ (an object-oriented language, based on C) C# (a Java-like language developed by Microsoft) Java MIT by S.Sabraz Nawaz 6

7 How a Computer Program Works The Program you write is executed by the CPU Since the CPU can only understand machine code your program needs to be converted into machine code MIT by S.Sabraz Nawaz 7

8 How a Computer Program Works Dim radius as integer Dim area as integer radius = txtradius.text area = 22/7*radius*radius msgbox area Source Code C8 B7 23A7 D7 AA 89 DD 89D23 A9 F4 A9... Machine Code MIT by S.Sabraz Nawaz 8

9 How a Computer Program Works Programmer writes the code in a high level language such as C++, Java, Visual Basic etc. Then using a software tool this high level code is converted into machine code The software tools that does the conversion to machine code comes in two flavours o Compilers o Interpreters MIT by S.Sabraz Nawaz 9

10 Compiling Source Code A program written in a high-level language is called a source program. Since a computer cannot understand a source program. Program called a compiler is used to translate the source program into a machine language program called an object program. The object program is often then linked with other supporting library code before the object can be executed on the machine. MIT by S.Sabraz Nawaz 10

11 Compilers and Interpreters Compiler o A compiler converts your entire program to machine code at one go o After compilation you have an executable file in machine code e.g. an EXE, COM file for PCs Interpreter o An Interpreter converts your program to machine code one instruction at a time MIT by S.Sabraz Nawaz 11

12 Developing Programs that run on Multiple Platforms You need to find a language that is supported by different platforms e.g. Visual Basic is only for PCs, C, C++ on the other hand are available for any type of computer MIT by S.Sabraz Nawaz 12

13 Developing Programs that run on Multiple Platforms We say that languages like C, C++ are portable at the source level o i.e. Since these languages have standards the program you write (source code) could be compiled on different platforms with little or no modifications MIT by S.Sabraz Nawaz 13

14 What makes Java Special? Java is platform independent at the binary level o i.e. If you write a program in Java and compile it you could run your compiled code on any type of computer When you compile a java program it does not produce machine code for a specific type of computer MIT by S.Sabraz Nawaz 14

15 How Java works? It instead creates machine code for a general virtual computer o This is referred to as java byte code o There are Java Interpreters available for almost all types of computer platforms To run your Java program you need the Java Interpreter installed in that computer It would convert the java byte code to the specific machine code of your computer MIT by S.Sabraz Nawaz 15

16 How Java works? MIT by S.Sabraz Nawaz 16

17 Program Development Process Text editor Saves Java statements Source code (.java) Java compiler Produces Byte code (.class) Java Virtual Machine Results in Program Execution MIT by S.Sabraz Nawaz 17

18 A Simple Java Program MIT by S.Sabraz Nawaz 18

19 Creating, Compiling, and Executing a Java Program MIT by S.Sabraz Nawaz 19

20 The Compiler and the Java Virtual Machine Most compilers translate source code into executable files containing machine code The Java compiler translates a Java source file into a file that contains byte code instructions Byte code instructions are the machine language of the Java Virtual Machine (JVM) and cannot be directly executed directly by the CPU MIT by S.Sabraz Nawaz 20

21 The Compiler and the Java Virtual Machine Byte code files end with the.class file extension The JVM is a program that emulates a micro-processor The JVM executes instructions as they are read JVM is often called an interpreter Java is often referred to as an interpreted language. MIT by S.Sabraz Nawaz 21

22 Java Virtual Machine The Java Interpreter is more popularly known as the Java Virtual Machine (JVM). It is also known as the Java Runtime This is available with the operating system of most computers today MIT by S.Sabraz Nawaz 22

23 Java Virtual Machine (a) Java source code is translated into bytecode. (b) Java bytecode can be executed on any computer with a Java Virtual Machine. MIT by S.Sabraz Nawaz 23

24 Sample Program MIT by S.Sabraz Nawaz 24

25 PRACTICAL WORK Example done for you

26 We use Java SE 7, Sun s latest version of Java language Basic types of Java programs. Java console applications Java GUI applications Java applets

27 Requirements.. In order to write a Java program we need: o o o An editor A Java compiler A Java Runtime Environment/Java Platform Editor Notepad, WordPad, etc. Java Compiler and Platform Sun s Java Development Kit

28 Java Development Kit This is a software package designed to help with the complete process of developing and running Java programs. It combine the functions of Compiler Interpreter Applet viewer Debugger

29 Example 1 Write a program to print, Hello, Welcome to MIT This program demonstrates how to write a simple java program.

30 Exercise 1 class Hello { public static void main(string[] args) { System.out.println("Hello, Welcome to MIT 12043"); } }

31 Example 1 class Hello { public static void main(string[] args) { System.out.println(" Hello, Welcome to MIT "); } } Name of Class

32 Example 1 class Hello { public static void main(string[] args) { System.out.println(" Hello, Welcome to MIT "); } } { - begin } - end

33 Example 1 class Hello { public static void main(string[] args) { System.out.println(" Hello, Welcome to MIT "); } } Main method (function). Java will perform the commands under this method.

34 Example 1 class Hello { public static void main(string[] args) { System.out.println(" Hello, Welcome to MIT "); } } Semi Colon ; indicates end of a command

35 Example 1 class Hello { } public static void main(string[] args) { System.out.println(" Hello, Welcome to MIT "); } Print Command in Java What ever in quotations will be printed as it is. i.e. Hello, Welcome to JAVA

36 Example 1 class Hello { public static void main(string[] args) { System.out.println(" Hello, Welcome to MIT "); } } Java like C and C++ is case sensitive i.e. if you type the first part of the as Public static void.. Your program will not work

37 Example 1 class Hello { public static void main(string[] args) { System.out.println(" Hello, Welcome to MIT "); } }

38 Compiling a Java Program To Compile your Java Program use the JDK s javac tool. E:\myjava>javac Hello.java The compiler would create java byte code. These files have an extension of.class

39 Running a Java Program To run your Java Programs you need to call the Java Interpreter. E:\myjava>java Hello

40 Example 2 Write a program that produces the following output Hello World! It's been nice knowing you. Goodbye world!

41 Example 2 - Solution 2 class HelloWorld { public static void main (String args[]) { System.out.println("Hello World!"); System.out.println("It's been nice knowing you."); System.out.println("Goodbye world!"); } }

42 Example 2 - Solution 2 class HelloWorld { } public static void main (String args[]) { } System.out.println("Hello World!\nIt's been nice knowing you.\ngoodbye world!"); \n is for new line

43 Exercise 1 Write a Java program using one println() statement to print your name and age on the screen. Your program should format the output as follows. Hello! I am SaNa. I am 36 years old.

44 Try these out Ex 01 MIT by S.Sabraz Nawaz 44

45 class DrawPicture { public static void main (String args[]) { System.out.println("* * * * * * "); System.out.println("* * * * * * * "); System.out.println("* * * * * * * *"); System.out.println("* * * * * * * * * *"); } }
