Short Introduction to the Java Programming Language

• Variables, data types, declarations, constants and operators
  • Names of variables
  • Data Types, Declarations and Initialisations
  • Unicode representation of char
  • Constants
  • Operators
    • Arithmetic operators
    • Assignment operators (applied to primitive data types)
    • Relational operators (applied to primitive data types)
    • Logical operators
    • Incrementing and decrementing operators
• Input and output
  • Write to the screen
  • Read from the keyboard via a dialog box
  • Write to a dialog box
  • Read from a file
  • Write to a file
  • Truncate
  • Displaying a graph
• Progam control
  • if statement
  • if else statement
  • Conditional operator ?:
  • for statement
  • while statement
  • do ... while statement
  • switch statement
• Methods
  The basic description of a method is given in the adjacent ComplexNumber Example: methods
  
  • Passing variables and instances to methods
    
    • Pass by value
    • Pass by Reference
    • Passing arrays
    • Use of copy and clone methods in passing instances
  • Standard mathematical functions (Math and Fmath)
  • Recursion
• Arrays
  • Arrays
  • Multi-dimensional arrays
• References in Java ('pointers')
  • Equality and Identity
  • Assignment Operator and Copying
  • Cloning and Arrays
• Inheritance
  • Simple example:
    
    • Component Example used to illustrate inheritance
    • Superclass, Component
    • Subclass, Resistor
    • Subclass, Inductor
    • Subclass, Capacitor
    • The circuit diagram of the circuit to be modelled in the application, ComponentExample [link below] illustrating the use of a superclass and its subclasses.
    • An application, ComponentExample.java using the above superclass, Component and subclasses, Resistor, Capacitor and Inductor
  • A more realistic example:
    
    • Transmission line example of inheritance
• Wrapper classes
  • Wrapper classes
  • String Conversion
  • Infinity
• Data Structure and the java Vector
  • Vector

• General
• A simple Java class and a simple Java application
• A simple Java applet
• ComplexNumber: an example of a Java class illustrating:
  • instance and static variables;
  • constructors;
  • methods:
    • set methods;
    • get methods;
    • methods performing mathematical operations:
      • instance and static methods;
    • method converting a complex number to a String;
  • overloading;
  • overriding;
• Good programming style
• Flow charts
