Java classes and objects

The class is defined as the blueprint a specific object.

The object consists by the “method” and “property”.

• A property is attributes of an object. It is like an adjective.
• A method is something we do to or on an object. It is like a verb.

To become a Java programmer we must learn two things: how to use classes that other people have created and how to create our own Java classes.

Question 1:

In the lesson, we used an analogy relating a recipe to a source file. Can you come up with your own analogy for the source file?

–

The source file is the one like the blueprint.

Question 2:

In your own words, describe the relationship between a Java source file, a file with a .class extension, and the Java compiler.

–

The Java compiler converts the source file into a file with a .class extension.

A souce file is human readable.
A .class file is machine readable.
