I need a quick approach to something like:

  MyClass mc = new MyClass();
  String theName = ClassNameProvider.getName(mc); // returns 'MyClass'

I think your requirement falls in the gap for apex but we have the ability to do one of following things:

We can retrieve the name of an object using code such as

String name = MyClass.class.getName(); //returns MyClass

We can check whether the instance of a particular type using

Boolean isSame = mc instanceof MyClass; //returns true

Or if we want to get the name from an instance of an unknown type we can do:

String name = String.valueOf(mc).split(':')[0];//returns MyClass

Hopefully one of those covers your need. See the discussion to a similar question here for more info.

    NOTE: String.valueOf(mc).split(':')[0] will not include the top level class for inner classes – NSjonas Oct 10 '16 at 18:15

    NOTE: That String.valueOf(mc) returns the toString() value of the class. The default return value is format of ClassName:[field1=value1, field2=value2,...fieldN=valueN] but if the class overrides the toString() method then this trick may not work for you. – Doug Ayers Jun 22 '18 at 4:54
  • Worth considering: String name = String.valueOf( mc ).substringBefore( ':' ) as it's just a little bit clearer – Rob Baillie Nov 7 '19 at 11:42

This is an interesting hack as posted on the idea Method to get the Type of an Object (also Primitive Type not only SObject) by Robert Strunk:

public static String getObjectType(Object obj){

    String result = 'DateTime';
        DateTime typeCheck = (DateTime)obj;
    catch(System.TypeException te){

        String message = te.getMessage().substringAfter('Invalid conversion from runtime type ');
        result = message.substringBefore(' to Datetime');

    return result;

The parse conversion exception approach overcomes the caveat that using String.valueOf(obj).split(':')[0] does not work in scenarios where the Apex class' toString() method has been overriden and returns a value in a different format, as pointed out in this comment.

To answer the title of the question: to get the name of the class from within any class use this:

String CurrentClassName = String.valueOf(this).substring(0,String.valueOf(this).indexOf(':'));

    Note the accepted answer recommends String.valueOf(mc).split(':')[0] among other approaches. This approach is just a slower version of that (you take String.valueOf twice). – Adrian Larson Apr 7 '17 at 13:17

    Actually, sometimes Paul's answer works better. Split-approach in some cases, for example within a loop, could reach a "Regex is too complicated" Salesforce Limit. – kvor Jul 5 '19 at 9:04
