Hi Smart,

The constructor is used to initialize the member variables in the class. Because every class will have the default constructor.

When we try to assign the values to the member variables out side the class then constructor is prefer method. Even it supports to do constructor overloading.

There is no need of writing a method to assign the values, because it can be assign the values at the time of creating object to the class.

Thats why constructor is preferred.

Because it's the most appropriate place to do it.

Before the code in the constructor even runs, all its instance fields (i.e. class level variables) are initialized to their default values. Unless a different value is specified in the field's declaration, the value used is 0 for numbers and enums, false for bool, '\0' for char, all bytes zero for other value types and null for reference types.

The constructor can then change these default values to more suitable values if, for example, such values are passed to the constructor as arguments.

Hi
because cunstructor is the member of the class which executes before starting execution of the other class member means cunstrocture executes when we create the instance of the class and if we need to initilize any another member of the class we can do it in custrocture. This is in case of public cunstrocture but in case of static cunstrocutur we can not say when it will execute but it's fix it will execute before any other member execution starts.
