What is initialization why is it important?
Initialization refers to defining a constant or variable values that are used in the code for executing a computer program.
Initialization plays a key role in programming as the variables that are used for writing the code occupy a certain amount of memory in the CPU.
Thus, initialization is very important..
What is Servlet life cycle?
A servlet life cycle can be defined as the entire process from its creation till the destruction. … The servlet is initialized by calling the init() method. The servlet calls service() method to process a client’s request. The servlet is terminated by calling the destroy() method.
What is Init method in Python?
“__init__” is a reseved method in python classes. It is known as a constructor in object oriented concepts. This method called when an object is created from the class and it allow the class to initialize the attributes of a class.
Is __ init __ a magic method?
Few examples for magic methods are: __init__, __add__, __len__, __repr__ etc. The __init__ method for initialization is invoked without any call, when an instance of a class is created, like constructors in certain other programming languages such as C++, Java, C#, PHP etc.
What does init mean in Java?
Instance Initialization method
When Init method is called?
The init method is designed to be called only once. It is called when the servlet is first created, and not called again for each user request. So, it is used for one-time initializations, just as with the init method of applets.
What is INIT in programming?
Initialization is the process of locating and using the defined values for variable data that is used by a computer program. For example, an operating system or application program is installed with default or user-specified values that determine certain aspects of how the system or program is to function.
What is the use of __ init __?
__init__ method “__init__” is a reseved method in python classes. It is called as a constructor in object oriented terminology. This method is called when an object is created from a class and it allows the class to initialize the attributes of the class.
What is print () in Java?
print(): print() method in Java is used to display a text on the console. This text is passed as the parameter to this method in the form of String. This method prints the text on the console and the cursor remains at the end of the text at the console.
What is Python method?
A method is a function that “belongs to” an object. (In Python, the term method is not unique to class instances: other object types can have methods as well. For example, list objects have methods called append, insert, remove, sort, and so on.
What is Servlet and its types?
servlet. … HTTP servlets provide a service method that automatically routes the request to another method in the servlet based on which HTTP transfer method is used. So, for HTTP servlets, override doPost() to process POST requests, doGet() to process GET requests, and so on.
What is __ str __ in Python?
Python says “__repr__” is used to get a string representation of object while __str__” is used to find the “informal” string representation of an object.
What is true Init method?
A – The init method simply creates or loads some data that will be used throughout the life of the servlet. B – The init method is not called again and again for each user request.
What is initializer in Arduino?
The member initializer list is specified after the arguments of the constructor. It begins with a colon followed by the name of each variable to initialize, separated by commas . The value to assign to each data member is specified between parenthesis after the name of each data member of the list.
What is super () in Python?
The super() function is used to give access to methods and properties of a parent or sibling class. The super() function returns an object that represents the parent class.
