Every non-static member function has a hidden pointer parameter named this which refers to the instance of the class the function was invoked against. For a given class, C, the type of the hidden this pointer is const C* but if the function is declared const, the pointer is const C* const. When referring to any class member, m, from within any non-static member function, this->m is implied.

What is the implicit name of the parameter that gets passed into the set method property of a class aData b Property c Value d Object?
Value, and its datatype depends on whatever variable we're changing.
What is the scope of method overloading and overriding?
Overloading happens when you have multiple methods in the current class that have the same name but different signature. The scope of method overloading is "Within the current class" Overriding happens when your current class extends another class (the parent class) and provides implementation for a method that is already available in the parent class. The scope of method overriding too is "Within the current class"
Can you pass object as an argument to a method?
if you have a function or a method that takes Object as a parameter, you can call that function or method and pass an Object as follows: Let's say you have a class that extends Object and a function as follows public class A extends Object { ..... } void function ( A arg ){ ..... } To call this function, you need an instance of the class A A objectInstance = new A(); function(objectInstance); The next line shows how to pass an instance of the class A to the function.
Which class has implicit instantiation?
All class from package java.lang is implicitly installed.
What is static void Main?
The String array args refers to the arguments that the program may require before starting. In many cases you may want the program to take some values as input for processing. this string array is for that purpose.

Why final method are used in java?
Final methods are used when a class is inheritable but should have some functions that must not be overridden for them to operate properly. This allows a class that can be inherited, but still have limits on its customization. Usually, final methods are declared so that a method that accepts a parameter of class A can accept a parameter of class B that inherits from A, and the designer of class A can still be certain that the method will operate as intended regardless of what the developer does in class B.

What is a value that is passed into a method when it is called?
Here is an example program that passes a Scanner object: import java.util.*; public class Conversion { public static void main(String[] args) { Scanner in = new Scanner(System.in); doSomething(in); } public static void doSomething(Scanner in) { int q = in.nextInt(); System.out.println("The value you entered is: " + q); } }

What is an implicit argument in java?
In Java, an implicit argument refers to an argument that is not explicitly provided by the programmer when calling a method. These arguments are typically provided by the language or the system environment automatically. Examples include the "this" reference in non-static methods and the default constructor arguments.
Can a main method in java be overloaded?
Yes. The main method is just like any other java method and can be overloaded. But - Only the method with public static void main(String[] args) signature will get invoked when the class is run.
Difference between Method overloading and method overriding in C plus plus?
Yes. Any base class method that is declared virtual can be overridden by a derived class. Overriding a method that is not declared virtual can still be called, but will not be called polymorphically. That is, if you call the base class method, the base class method will execute, not the override. To call a non-virtual override you must call it explicitly.
