No cell phones
No latecomers
Feel free to remind your classmates

• Lots of hard work and learning
– Take responsibility for your learning
– Read the assigned reading before lecture
– Look at the assignments when they are posted

• Fun and Magic
– Programming is creating something from nothing

How Much Effort to Put Into This Course?
• This is the foundation for the other programming courses in CST
– More Java, C, C++, C#

• All second year options have programming content • Comp 1510 is a prerequisite to three second term courses
– Comp 2510 C, Comp 2526 Java II, Comp 2721
Architecture
– You will be blocked from these without this course

• Be sure to master this course!!!

Java
• The Java programming language was created by
Sun Microsystems, Inc.
• It was introduced in 1995 and it's popularity has grown quickly since
• A programming language specifies the words and symbols that we can use to write a program
• A programming language employs a set of rules that dictate how the words and symbols can be put together to form valid program statements

Java Program Structure
• In the Java programming language:
– A program is made up of one or more classes
– A class contains one or more methods
– A method contains program statements

• These terms will be explored in detail throughout the course
• A Java application always contains a method called main • See Lincoln.java

Comments
• Comments should be included to explain the purpose of the program and describe processing steps • They do not affect how a program works
• Java comments can take three forms:
// this comment runs to the end of the line
/*

this comment runs to the terminating symbol, even across line breaks

/** this is a javadoc comment

*/

Identifiers
• Identifiers are the "words" in a program
