Call One Constructor from Another Constructor

Constructor is a special kind of method which gets called automatically whenever the object is created. One class can have zero, 1 or more then 1 constructors. Basically, you can overload constructor method.

Now that you can have more then one constructor, you may want to reuse the code that you write in different constructor methods. Java provides you a mechanism by which you can call one constructor method from another. The way you achieve this is that the first statement of one constructor should call another constructor using the "this" object reference.

Here is a sample code which shows the technique of calling one constructor from another.

 
class MyClass
{   // default constructor
    public MyClass()
    {
	this("", 0);
    }
Another constructor:
 
    public MyClass(String strSomeName, int intSomeAge)
    {
	this.strName = strSomeName;
	this.intAge = intSomeAge;
    }
Private member variables:
 
    private String strName;
    private int intAge;
}
