Java will not sound the death knell of structured programming. It will, however, give programmers a viable choice. Classes Classes are the backbone of Java. Classes are the manner in which objects are created and modified. When you create an instance of a class, you create an object.
Classes have methods and inheritance the same as objects.
In many ways classes are merely objects by another name. To use a class, the class must be declared and constructed. By this I mean the first step in utilizing a class in a Java program is to declare it. Once the class has been declared, you must use the new constructor to fully create the object. I will discuss both procedures more fully.
