Solution

The method of the Object class used to obtain the class of an object at run time is the getClass() method. Here are the steps to use it:

  1. First, you need to have an instance of a class. For example, let's say we have a class named "MyClass" and we create an instance of it:
MyClass myObject = new MyClass();
  1. Now, to get the class of this object at runtime, you use the getClass() method:
Class<?> clazz = myObject.getClass();
  1. You can then use this Class object to get information about the class, such as its name:
String className = clazz.getName();

So, the getClass() method is used to obtain the class of an object at runtime.
