For the Java programmers, this may make it easier to navigate around and find the resources you need.
Use the shortcut Ctrl + F to find what you need, or you can scroll down through the categories and see. If you can't find what you need here, the [Image: search.gif] Search button is your best friend.



What is Java?

Quoting Wikipedia:
Java is a programming language originally developed by James Gosling at Sun Microsystems (which is now a subsidiary of Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. Java is general-purpose, concurrent, class-based, and object-oriented, and is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere". Java is considered by many as one of the most influential programming languages of the 20th century, and widely used from application software to web application.

There were five primary goals in the creation of the Java language:

It should be "simple, object oriented, and familiar".
It should be "robust and secure".
It should be "architecture neutral and portable".
It should execute with "high performance".
It should be "interpreted, threaded, and dynamic".

Syntax

The syntax of Java is largely derived from C++. Unlike C++, which combines the syntax for structured, generic, and object-oriented programming, Java was built almost exclusively as an object oriented language. All code is written inside a class and everything is an object, with the exception of the intrinsic data types (ordinal and real numbers, boolean values, and characters), which are not classes for performance reasons.

Practice problems


Write a program which will read in three numbers and print the average value of the numbers. Try out the program. Does it produce the answers you expect?
A sample session with the user might look like:
Enter three numbers
5
10
15
The average is 10



Write a program that reads in a person's height in centimeters and converts it to light years. One light year is the distance that light travels in a year. The speed of light is 2.99793e8 meters per second.


This 3rd one is a little harder than the first two.



Write a program that asks the user for an amount of money (a number of cents less than one euro). It should then calculate the smallest number of coins that make up the sum of money. A sample run of the program would be
How many cents (0 - 99): 46
50: 0
20: 2
10: 0
5: 1
2: 0
1: 1
