Java Class - getCanonicalName() Method

The java.lang.Class.getCanonicalName() method returns the canonical name of the underlying class as defined by the Java Language Specification. Returns null if the underlying class does not have a canonical name (i.e., if it is a local or anonymous class or an array whose component type does not have a canonical name).


public String getCanonicalName()


No parameter is required.

Return Value

Returns the canonical name of the underlying class if it exists, and null otherwise.




The example below shows the usage of java.lang.Class.getCanonicalName() method.

import java.lang.*;

public class MyClass {
  public static void main(String[] args) {
    MyClass x = new MyClass();
    Class cls = x.getClass();

    //print the CanonicalName of the class
    String name = cls.getCanonicalName();
    System.out.println("CanonicalName of class = " + name);

The output of the above code will be:

CanonicalName of class = MyClass
