public class ClassgetCanonicalNameExample1 {

   public static void main(String[] args) {

      ClassgetCanonicalNameExample1 clsobj = new ClassgetCanonicalNameExample1();
      Class clsobj2 = clsobj.getClass();

      // returns the canonical name of the class if it exists
      System.out.println("Class Canonical Name = " + clsobj2.getCanonicalName());  // get canonical name

Class Canonical Name = ClassgetCanonicalNameExample1
Class Simple Name   = ClassgetCanonicalNameExample1

Example 2

//import statements?

public class ClassgetCanonicalNameExample2  {

   public static void main(String[] args) {

     ClassgetCanonicalNameExample2  cobj = new ClassgetCanonicalNameExample2 ();
     Class clsobj = cobj.getClass();
     System.out.println("Class = " + clsobj.getCanonicalName()); //get canonical name
   }
}
