What are the oop concept of java

Answers

Answer 1

Answer: OOP concepts in Java are the main ideas behind Java’s Object Oriented Programming. They are abstraction, encapsulation, inheritance, and polymorphism. Grasping them is key to understanding how Java works. Basically, Java OOP concepts let us create working methods and variables, then re-use all or part of them without compromising security.

HOPE THIS HELPED IS NOT SORRY.

Answer 2

OOP stands for Object Oriented Programming. In Java, we create classes to represent different things. For instance:

public class MyClass {

   public static void main(String args[]) {

     Car cr = new Car();

     cr.createCar("Ford", "Green", 2000);

     cr.printInfo();

   }

}

class Car{

   private String model, color;

   private int year;

   

   void createCar(String md, String cl, int yr){

       model = md;

       color = cl;

       year = yr;

   }

   void printInfo(){

       System.out.println("Car Info:");

       System.out.println("Model: "+model);

       System.out.println("Color: "+color);

       System.out.println("Year: "+year);

   }

}

We create a car object derived from the Car class with whatever properties we want and then we can display the properties of our car with the printInfo() method.

This is just one example of the OOP concept of Java.

For an indirect reference, what happens if there is no list of limited values authorized for a user in the direct reference?

a. SQL Injection
b. Brute Forcing of stored encrypted credentials
c. XML Injection
d. Access to sensitive data possible

Answers

Answer: Access to sensitive data possible

Explanation:

A reference is a value that allows a particular datum to be accessed indirectly by a program.

It should be noted that when there is no list of limited values authorized for a user in the direct reference, this will lead to a possibility for an access to sensitive data. Therefore, in order for this to be prevented, there should be a list of limited values that will be authorized for a user.

The absence of a list of limited values which would restrict access to certain files or data will lead to vulnerability of sensitive data. Hence, access to sensitive data possible.

The possibility of data being assessed by an unauthorized user is very likely when there is no restriction.

The reference is supposed to be key as a key to control the level of access given to users by providing a list of limited authorized values.

Hence, when these list is absent, then, access to sensitive data possible becomes very likely.

__init__(self, features, phones): create/initialize instance variables for features and the list of phones (optional) in the plan. When phones is not provided, use an empty list as its initial value. Create an instance variable

Answers

Answer:

class Phone(object):

   def __init__(self, features, phones=[]):

       self.features = features

       self.phones = phones

Explanation:

In python object-oriented programming, an instance variable of a class object is created in the "__init__()" method. the "self" is a convention name used to represent the instance of an object class. The input values are assigned to the object variable with the self.'argument_name' statement.

When the phone argument is not given, the self.phones variable is initialized as an empty list.

A local bank has just one branch. It sets up a peer-to-peer network for all devices on the system. The bank would like to be able to have one technician administer the entire network from his location outside the bank without having to go to the bank each time there is a problem. Will this be possible for the technician?

A. It will not work because it is not possible to have the technician administer from one single location.

B. It will not work because the bank needs to use a server in a central location to allow for the remote access.

C. It will work as long as a LAN network is established to facilitate the communication between devices.

D. It will work if it uses a WAN to bring in all of the LANs to one central location.

CORRECT ANSWER IS B!

Answers

B
Good luck hope you get a good grade

It will not work because the bank needs to use a server in a central location to allow for the remote access, hence option B is correct.

What is a peer-to-peer network?

A distributed application architecture known as peer-to-peer computing or networking divides jobs or workloads across peers.

Peers are equally qualified and capable members of the network. They are referred to as the nodes in a peer-to-peer network.

In the hypothetical situation, the technician is unable to manage the complete network from outside the bank. Every time a problem arises, the technician must visit the bank.

Therefore, in order to give them the desired remote access, I need a server that is situated in a strategic location, hence option B is correct.

Give the pseudocode of a data structure that supports the stack push and pop operations, and a third operation findMin, which returns the smallest element in the data structure, all in O(1) worst-case time.

Answers

Answer:

start Stack push:

IF stack is full

   return NULL

ENDIF

stack_top = stack_top + 1

stack[ stack_top] = data

end

start stack pop:

IF stack is empty

   return NULL

ENDIF

data = stack[ stack_top]

stack_top = stack_top - 1

end

start stack findMin:

SORT stack in ascending order

min = stack[0]

RETURN min

end

Explanation:

Pseudocode is the description of an algorithm to be used to implement a program code. The pseudocode above describes the step by step implementation of the stack data structure 'push', 'pop', and a new 'findMin' function. The findMin function sorts and gets the minimum value of the elements in the stack. The push and pop operators add and remove items from a stack.

The pseudocode of all three functions does not iterate over the stack element, but gets the constant values of an item in the stack, giving it a time complexity of 1 (O(1) in big-O notation).

A manufacturer of scented candles is preparing to produce five new candles with fragrances of peppermint, cinnamon, lemon, spice pumpkin, and pine scents to sell for the holiday season.

An array that will hold the names of the 5 new scented candles and another array that holds the count of the 5 new scented candles that are sold over the next couple of months. The program will track the fragrance type of the candle purchased and the number of candles sold for each fragrance.
