Get the fully-qualified name of a class in Java

A fully-qualified class name in Java contains the package that the class originated from. An example of this is java.util.ArrayList. The fully-qualified class name can be obtained using the getName() method.

A program that demonstrates this is given as follows −

Example

 Live Demo

public class Demo {
   public static void main(String[] argv) throws Exception {
      Class c = java.util.ArrayList.class;
      String className = c.getName();
      System.out.println("The fully-qualified name of the class is: " + className);
   }
}

Output

The fully-qualified name of the class is: java.util.ArrayList

Now let us understand the above program.

The getName() method is used to get the fully-qualified name of the class c which is stored in className. Then this is displayed. A code snippet which demonstrates this is as follows −

Class c = java.util.ArrayList.class;
String className = c.getName();
System.out.println("The fully-qualified name of the class is: " + className);
