Constructor is a crucial concept in java that help us to declare object, parameterization and customization. 6. Garbage collection in java is a concept where unused reference of object is destroyed to free the memory space occupied by the object. 7. Dynamic Method Dispatch in Java is the process by which a call to an overridden method us resolved at runtime. 8. final is the keyword which is used before the variable to make constant the value of variable and finally is block which is used in exception handling that prints any statement repeatedly. 9.

Explain for-each statement with suitable example. In Java, the “for-each” loop is a specialized loop designed for iterating over elements in arrays, collections, or other iterable data structures. It provides a more concise and readable way to iterate through these elements compared to traditional “for” or “while” loops. The for-each loop is also known as the “enhanced for loop” or the “foreach loop.” we can understand with the help of following code: Long Answer Questions This is the example of unchecked exception: Comprehensive Questions 20.Explain the OOP principal followed by Java. What are the restrictions when themethod is declared as static? Write a java program to illustrate the concepts of staticmethod. Java is an object-oriented programming (OOP) language, and it follows several key OOP principles, including: Regarding your question about static methods, here are some key points and restrictions when a method is declared as static in Java: Here’s a Java program illustrating the concept of a static method: Inheritance is one of the fundamental concepts of object-oriented programming (OOP) that allows you to create a new class based on an existing class. Inheritance enables a class to inherit the properties (fields) and behaviors (methods) of another class, known as the superclass or base class. The new class is called a subclass or derived class. In essence, the subclass is a specialized version of the superclass. Advantages of Using Inheritance: Different Types of Inheritance: Multiple Inheritance (Interface Inheritance): Multilevel Inheritance:

Price Hacking

Price hacking is a term used to describe the act of manipulating prices through the use of technology, algorithms or the other techniques to gain an unfair advantage in the marketplaces. This practice has become increasingly prevalent in recent years, particularly in the e – commerce industry. In this essay, we will discuss the causes, effects and the potential solutions to price hacking. The causes of price hacking are varied, but they often stem from the intense competition in the e commerce industry. Retailers are constantly looking for the ways to attract customers and increase sales and offering the lowest price is one of the most effective ways to do so. In some cases, retailers may resort to price hacking to gain unfair advantages over their competitors. The effects of price hacking can be significant both for consumers and for the broader economy. Consumers may be misled into believing that they are getting a better deal that they actually are, which can erode trust in the marketplace.it also leads to the unsustainable market instability. Potential solutions to price hacking are the complex and may require a multifaceted approach. One approach is to increase transparency in the market place. For example, by requiring retailers to disclose the algorithms and pricing strategies they use. This would allow consumers to make more informed decisions and being misled by price hacking tactics. Another approach is to strengthen antitrust laws and regulations to prevent retailers from engaging in unfair practices that distort competition. Technology also has a role to play in combating price hacking. For example, artificial intelligence and machine learning algorithms can be used to detect and identify instances of price hacking, allowing regulators and law enforcement to take action against the responsible parties. in addition, block chain technology could be used to create a more transparent and secure market place. In conclusion, price hacking is a growing trend in e commerce and online market place that allows consumers to take the advantages of loophole in pricing models to obtain products and services at a lower market value.
