Every class in the Java programming language has a name. When you declare a class, the name
immediately follows the class keyword. In the following class declaration,
the class name is Point:
public class Point {int x, y;}
At runtime, you can determine the name of a Class object by invoking the
getName method. The String returned by getName is the fully-qualified
name of the class.
The following program gets the class name of an object.
First, it retrieves
the corresponding Class
object, and then it
invokes the getName method on that Class object.
import java.lang.reflect.*;
import java.awt.*;
class SampleName {
public static void main(String[] args) {
Button b = new Button();
printName(b);
}
static void printName(Object o) {
Class c = o.getClass();
String s = c.getName();
System.out.println(s);
}
}
The sample program prints the following line:
java.awt.Button
