Cast from String or Serializable value to a Class Object;

I have an enum Class Property and in some part of my programm I want to replace a String or Serializable value in my Property. How can i do that?

public enum Property {
    Autofocus,
    Bluetooth,
    Brand,...}

How can i assign value to Property using a Serializable value or a String:

Property property;
this.property = (Serializable) value;

or

this.property = "value";

instead of 

this.property = Property.Autofocus;
this.property = Property.Brand; // ...

Property.valueOf("Bluetooth");

will take the value from string to the value of the enum if that's what you meant

The static methods valueOf() and values() are created at compile time and do not appear in source code. They do appear in Javadoc, though; for example, Dialog.ModalityType shows both methods.

Use java.lang.Enum.valueOf(Class<T> enumType, String name):

Property p = Enum.valueOf(Property.class, "Autofocus");
System.out.println(p);

Every enum has an implicit method valueOf(String) that returns the enum instance with the specified name:

 Property p = Property.valueOf("Autofocus");

Note that this method throws an IllegalArgumentException for unknown values.
