Topics continued from above:

Get data from user using JOptionPane class & use Control Structure
(nested if - else if): Calculator2.java

Get data from user using JOptionPane class & use Control Structure (Switch() ): Calculator3.java,

Using Scanner class to input data: ScannerTest1.txt , ScannerTest2.txt, TestScanner.html , Calculator4.java

Also see corresponding notes and lectures from my Spring 0002 class

Using the Scanner Class to input data (read data from an input stream (the keyboard since we are using System.in))

Reference (Only these methods for now):
Scanner data = new Scanner(System.in); // create a scanner object

String variablename = data.next() // Reads next "token", a "word" stops when finds white space

int variablename = data.nextInt() // reads an integer value.

double variablename = data.nextDouble() // reads a double value.

String lineoftext = data.nextLine() // Reads a line of text

* use System.out.println() before using Scanner class's methods to inform user of what type of data to enter.

Repetition Structure(Iterations using Loops): Calculator5.java , Calculator6.java

Readings: Chapter 6

Arrays II(starting at slide 99)

File I/O (Reading data from a file and writing data to a file within a program): Chapter 8 (pages 283- 291)

Java has many techniques to read/write to a file (I/O):

1) Simple example using File class:

• TestFileClass.java

2) Reading from File: A simple example using Scanner and File class:

Read from file || life2.dat (you can use any data file for this example but you need to change the name of the file)

Two examples that will help read from files for assignment # 4 (Game of life):

1) Initializing a TicTacToe board from data in a file called tic.dat (helpful for assignment#4): Three files needed:

Version #1: TestFileStringReader2.java ||FileStringReader.java || tic.dat

Version #2: Same example as above but using Scanner class (easier to use and more efficient):

ScannerFileReader || TestFileScanner || tic.dat

Chapter 8: File I/O lecture

Abstract class and Interfaces ( Chapter 11)

• Abstract classes (
  • Geometric Object || TestGeometricObject
    

Reading Chapter 11 (lecture)

review lecture of Abstract class and Interfaces

• Max.java
• A generic sort using Comparable interface :
  • GenericSort.java: use one method that takes an Object type as a parameter to sort objects of different types: Integer, Double, Character (wrapper classes ) .

Review Sort an array list using comparable interface:

• TestEmployee.java || Employee.java

Using ArrayList (data structure) to store objects: TestArrayList example
