throws ClassNotFoundException
{
// returns the Class object for this class
Class myClass = Class.forName("Test");
System.out.println("Class represented by myClass: "
+ myClass.toString());

// using getSuperclass() method
System.out.println("Superclass of myClass: "
+ myClass.getSuperclass());
}
}
输出:
Class represented by myClass: class Test
Superclass of myClass: class java.lang.Object
例 2:
// Java program to demonstrate getSuperclass() method
public class Test {
class Arr {
}
public static void main(String[] args)
throws ClassNotFoundException
{
// returns the Class object for Arr
Class arrClass = Arr.class;
// Get the super class of arrClass
// using getSuperclass() method
System.out.println("Superclass of arrClass: "
+ arrClass.getSuperclass());
}
}
输出:
