What are object methods?
A method in object-oriented programming (OOP) is a procedure associated with a message and an object. An object consists of data and behavior; these comprise an interface, which specifies how the object may be utilized by any of its various consumers.
Do objects have methods?

What are methods in object class?

| protected Object clone() throws CloneNotSupportedException | creates and returns the exact copy (clone) of this object. |
| public String toString() | returns the string representation of this object. |

- protected Object clone() throws CloneNotSupportedException.
- public boolean equals(Object obj)
- protected void finalize() throws Throwable.
- public final Class getClass()

How are object methods used in the real world?
Object methods, “this” Objects are usually created to represent entities of the real world, like users, orders and so on: let user = { name: “John”, age: 30 }; And, in the real world, a user can act: select something from the shopping cart, login, logout etc.

What happens when you change an object in a method?
If you change a member of the object by using this reference, the change is reflected in the object when control returns to the calling method. However, replacing the object passed to the method has no effect on the original object when control returns to the caller.
Are there any methods that inherit from an object class?
Since all types in the managed type system inherit directly or indirectly from the Object class, all types inherit its members, such as Equals (Object), GetType (), and ToString (). The following example defines a Person class, instantiates two Person objects, and calls the Person.Equals method to determine whether the two objects are equal.
