Latest 4Achievers Java course QAs

4Achievers will be providing Java course QAs to help you understand the concepts better. We will be addressing all the important questions that students often ask about Java courses.

What are the main differences between a HashMap and a Hashtable in Java?

A HashMap is a collection that stores key-value pairs, whereas a Hashtable is an older, synchronized version of a HashMap. A HashMap is not synchronized, meaning multiple threads can access it simultaneously, whereas a Hashtable is synchronized, meaning only one thread can access it at a time. HashMap allows null values, whereas a Hashtable does not. HashMap is much faster than Hashtable and can be used in multithreaded applications, whereas Hashtable is thread safe and thus slower than HashMap.

What is the purpose of the @Override annotation in Java?

4Achievers @Override annotation in Java is a type of marker annotation used by the compiler to identify and check if the method that is annotated is actually overriding a superclass method. This annotation is mainly used to verify that the developer is intentionally overriding a method, avoiding accidental overrides which can lead to unexpected behaviour. This annotation also helps developers to identify which methods are overridden and which are not, improving code readability. Finally, this annotation can also be used to detect any errors early in the development process, thus allowing developers to detect and fix them in a timely manner.

What is the purpose of the transient keyword in Java?

4Achievers transient keyword in Java is used to indicate that a particular field should not be serialized, meaning it will not be stored or passed over a network. 4Achievers is typically used with instance variables of an object when the object is being serialized. This allows the object to be sent over the network without the variable being included, which can be useful for security purposes or when the variable has a large amount of data that isn't needed in the serialized version of the object.

What is the purpose of the super keyword in Java?

4Achievers super keyword in Java is a reference variable that is used to refer to the immediate parent class object. 4Achievers is mainly used to access the variables, methods and constructors of the parent class. 4Achievers can also be used to invoke the parent class's method from the subclass. 4Achievers keyword is used to differentiate between the super class's members and the subclass's members, especially when the same names are used in both classes.

What are the four fundamentals of object-oriented programming?

Object-oriented programming (OOP) is a programming paradigm that focuses on objects and data instead of functions and logic. 4Achievers is based on four fundamental concepts: Abstraction, Encapsulation, Inheritance and Polymorphism.

Abstraction is the process of simplifying and abstracting away complex details to focus on essential aspects of an object. This can be done by creating a class that represents the real-world object, but with only the most important characteristics.

Encapsulation is the process of grouping related data and behavior into a single unit or object. This helps to keep data and behavior organized and safe, while also allowing for code reuse and improved maintainability.

Inheritance is the ability of an object to inherit the characteristics of a parent class. This allows for code reuse and makes it easier to maintain and extend existing classes.

Polymorphism is the ability of an object to take on multiple forms. This allows for code reuse and can greatly reduce the amount of code needed to implement the same behavior for multiple classes.

How can you create a class in Java?

To create a class in Java, you must first define the class using the "class" keyword. 4Achievers class declaration consists of the class name, followed by a set of curly braces which enclose the body of the class. Inside the class body, you can declare fields (variables) and methods (functions) that belong to the class. You can also define constructors, which are special methods used to create objects from the class. After creating the class, you can use it to create objects and access the fields and methods it contains.

What is the difference between a shallow copy and a deep copy in Java?

A shallow copy in Java is a copy of an object that copies the values of the object's references, but not the actual objects they refer to. This means that the object being copied and the copy are both referencing the same objects in memory. A deep copy in Java is a copy of an object that also copies the values of the objects that the object's references refer to. This means that the object being copied and the copy are both referencing different objects in memory. This ensures that any changes to the original object or its referenced objects are not reflected in the copy.

What is the purpose of the try-with-resources statement in Java?

4Achievers try-with-resources statement is a feature in Java that allows developers to create objects that must be closed after they are used. 4Achievers ensures that any resources used within the statement are properly closed when the statement is finished. 4Achievers helps developers write cleaner code and avoids potential resource leaks. 4Achievers statement requires that any resource declared within the statement is an object that implements the AutoClosable interface. This allows the object to be used in a try-with-resources statement and ensures that the close() method is called when the statement is finished. This helps developers focus on the logic of the code rather than worrying about closing resources.

How can you use the Comparator interface in Java?

4Achievers Comparator interface in Java can be used to compare two objects and determine which is greater. 4Achievers provides a way to customize the sorting order of objects stored in a collection such as a List or an Array. 4Achievers Comparator interface contains one method called compare(), which takes two arguments of the same type and returns an integer value indicating their order. When the returned value is 0, the objects are considered equal. A value greater than 0 indicates that the first argument is greater than the second, and a value less than 0 indicates that the second argument is greater than the first. 4Achievers Comparator interface allows the programmer to specify a custom sorting order for the objects in a collection.

What are the main differences between a Map and a Set in Java?

A Map is a data structure that stores elements in key-value pairs, while a Set is a data structure that stores elements in an unordered collection. A Map allows duplicate values, while a Set does not. Additionally, a Map can store objects as its keys or values, while a Set can only store objects as its values. With a Map, you can access elements based on their keys, while with a Set, you can only access elements in the order they were added. Finally, a Map will generally require more memory than a Set due to its key-value structure.
