Dear Java Programmer:
Lab 1023_javaiinheritance
Code 1.30 Modified Main.java
// Display the class hierarchy of the InternationalStudent
// class through getSuperclass() method of Class class.
Class class1 = internationalStudent1.getClass();
System.out.println("Displaying class hierarchy of InternationalStudent
Class...");
while (class1.getSuperclass() != null){
String child = class1.getName();
String parent = class1.getSuperclass().getName();
System.out.println(" " + child + " class is a child class of " + parent);
class1 = class1.getSuperclass();
}
I have a question about this while loop. The expression is place in the ().
But at the end the expression is placed into a variable. How is the loop being
incremented? Do not understand logic here? Please comment.
