Top Ten Tips

0) Hello World

Some short, trival programs.

1) Data types

Creating variables of different types. Converting between variable types.

2) Control structures

We control program flow with while, for, foreach, if, return, break and other constructs

3) Tests

We look at the different ways to test conditions.

4) In-built function

We can use many functions provided by the core language. String and number functions primarily.

5) In-built data structures

We can make use of arrays, hash tables and dates.

6) Input and output

We explore the options for reading and writing data to files and to databases.

7) Graphics

Drawing lines, polygons, strings and other shapes.

8) Graphic User Interface

Buttons, text boxes that users can see and control.

9) Programming techniques

Accumulating variables, recursion, function composition.

• Use progzoo from Eclipse
• In case of emergency. Batch files and Java programs so you can run on your own machine.
• Java documentation from Sun. Look at java.lang and java.awt
• Wiki Write your own tutorials.
• Is it safe?
