7. Hardware components
Software and programming
Introduction to Java
Integrated Development Environment
(IDE
IDE)
IDE

8. Central Processing Unit (CPU)
Persistent Data Storage
◦ Hard Drive, CD, Diskette, ROM
Volatile Storage
◦ Random Access Memory (RAM)
Peripherals
◦ Mouse, Keyboard, Screen, etc

9. Instructions that tell the hardware
what to do
Three ways to obtain software
◦ Buy pre-written software
◦ Modify pre-existing software
◦ Write the software

10. Tools for the user
Usually a collection of programs
Provide a user interface
◦ Accept input
◦ React to requests
Examples: Microsoft Office, Netscape
Navigator

11. Program that controls the computer
hardware
Provides a consistent way for
applications to access the hardware
Many Operating Systems exist, mostly
incompatible with each other
Applications must be written
specifically for the target Operating
System

12. Digital CPUs require binary instructions
Early computers were programmed with
electrical switches
Very difficult to write programs
Early languages used mnemonics that
were translated to binary for the CPU
Higher-
Higher-level languages allow the
programmer to ignore the details

13. Early high-level languages were procedural
Programs were a list of sequential steps
Programmer had to think like the computer
Object-oriented Programming (OOP) uses
general purpose components
Components are then assembled in to an
application

14. Components are called ‘Objects
Objects’
Objects
Object perform specific functions
Objects interact by sending & receiving
messages
Programmer is focused on coordinating the
object interaction
Closely models human problem-solving
problem-

15. Punctuation – Symbols used
Vocabulary – The languages keywords
Identifiers – Used to reference data
Operators – Symbols representing commands
Syntax – Rules for combining the language’s
elements

16. Compiled – The program is translated in to
the CPU’s binary language once it is
completed
Interpreted – The individual instructions in
the program are translated immediately
before they are executed

17. Originally designed for consumer devices
Had to be small, simple, portable
small simple
Ideal for use over the Internet

19. Java programs written as text files
Java compiler creates a program file
consisting of ‘Byte Code
Byte Code’
The byte-code file is sent to the target
computer, which has a Java Virtual Machine
(JVM)
The JVM ‘interprets the byte-code, one
interprets’
interprets
instruction at a time
A Separate JVM is required for each
Operating System & CPU

21. Create Java Programs with a text editor or
Integrated Development Environment (IDE)
Use a compiler to create the ‘byte-code’ class
files (Such as JDK)
A Java Virtual Machine (JVM on the target
JVM)
JVM
computers

// This program will say hello Class definition
public class sayHello { Data & methods
public static void main(String args[]) {
String name = “Student”;
int number = 1; The ‘main’ method
System.out.println(“Hello”);
System.out.println(name); Punctuation
System.out.println(“Your lucky number is “ + number);
}
