Four ways to initialize instance variables
There are at least four ways to establish initial values for instance variables (you may be able to think of others) :
Using the first two ways
The following fragment illustrates the first two of those four ways.
class Worker{
private int myInt = 100;private double myDouble = 222.0;
private boolean myBoolean;//... In the above fragment, the instance variables named myInt and myDouble receive their initial values from initialization expressions. In these twocases, the initialization expressions are very simple. They are simply literal expressions. However, they could be much more complex if needed.
The variable named myBoolean in the above fragment is allowed to take on its default value of false.
Replacing the default noarg constructor
The next fragment shows one of the two overloaded constructors in the class named Worker . This constructor is a replacement for the default noarg constructor.
