Question

How do we initialize the constant data members of a class when an object is initiated? Give an example.

Answer 1

In Java, you'd use either a constructor or specified values in the declaration:

class MyClass {
int myValue1 = 3; // One way
int myValue2;

MyClass() {
myValue2 = 5; // Another way
}
}

Answer 2

Constant data members in a class aren't initialized during instantiation of an object at all; they're initialized when the class is defined:

public class MyClass {
public static final int MY_CONSTANT = 10;
/* remainder of class definition */
}
