when initializing a class elements by using constructor it will assigned to the elements when object creation is going on.
by using other ways the elements will be initialize with default values when object creation
An implicit constructor call will always call the default constructor, whereas explicit constructor calls allow to chose the best constructor and passing of arguments into the constructor.
Every class has at least one it's ownconstructort. Constructor creates a instance for the class. Constructor initiates (initialize) something related to the class's methods. Constructor is the method which name is same to the class. But there are many difference between the method (function) and the Constructor. In this example we will see that how to to implement the constructor feature in a class. This program is using two classes. First class is another and second is the main class which name is Construct. In theConstruct class two objects (a and b) are created by using the overloaded another Constructor by passing different arguments and calculated the are of the different rectangle by passing different values for the another constructor.
Functions and Constructors are similar in many ways. They can have arguments, they can have any amount of code, they can access the class's variables etc. the only difference is that a method in java needs to mandatorily have a return type but a Constructor in java cannot have a return type. It always creates and returns an object of the class for which it is the constructor. You cannot return a value from a constructor explicitly and if you try to do that, the compiler will give an error. The system knows that the purpose of the constructor is to create an object of the class and it will do the same irrespective of whether you declare a return type or not.
A constructor is a method that fires when the object is instantiated. A friend function is a function that has special access to the object. They are two different types of things, and cannot be further differenced.
A default constructor is one that has no parameters (C++ also calls constructors with all default parameters a default constructor), while a parameterized constructor is one that has at least one parameter without a default value. Default constructors can be provided by the compiler if no other constructors are defined for that class or any class the class inherits from, while parameterized constructors must always be defined by the developer.
An implicit constructor call will always call the default constructor, whereas explicit constructor calls allow to chose the best constructor and passing of arguments into the constructor.

These concepts are two different things. A 'Constructor' is a special method with the same class name and with no return type definition, invoked only when we create a new object (when we instantiate our object with the 'new' operator). An is used to initialize our object state (our instance variables). A thread is a separate process which runs in parallel (at the same time) in a program.
Explain the difference between the elements of the communication process and the communication process

In a declarative statement, you initialize the object. But in an imperative statement, you use a preexisting statement and use it.
the ease with which the elements can be separated.

is the same
Well 'while' goes like this: while (condition) statement 'for': for (initialize; condition; after-each-loop) statement
