Section 4 quiz Friday!
Friday is the last day for submitting Section 4 work.

Introduction to If Statements and Conditionals
if( condition goes here - must evaluate to either true or false)
{
this code is executed if the condition evaluates to true.
}
else - is optional
{
this code is executed if the condition evaluates to false.
}

Instead of an else statement you can also use an else if statement
if( condition)
{
this code is executed if the condition evaluates to true.
}
else if(condition)
{
this code is executed only if the first if condition was false and the second if condition was true.
}

Common Mistakes with If/Else statements - placing a ; after the condition, this exits the if statement

Homework

Install Eclipse on your home computer if you would like to be able to work on your java at home.

What

In this lesson, you will learn how to:
•Recognize the correct general form of a class
• Create an object of a class
• Describe object references
• Create methods that compile with no errors
• Return a value from a method
• Use parameters in a method

Why

Class templates are the foundation of the Java language. Understanding how to create a class with various methods will be essential to becoming a good Java programmer. Knowing how to instantiate an object and compare it to other objects is critical to learning to use and work with Java data types.

How

By completing the slides, quiz and practice exercises.
