In Java, the final keyword is used to restrict the user. The final keyword in Java can be used in a variety of situations. Finally, you could say: variable method class The final keyword can be used with variables to create a final variable with no value. It’s also known as an uninitialized final variable […]

In Java, the static keyword is mostly used to control memory. It is also used to share a class’s identical variable or method. Static keywords can be used with variables, methods, blocks, and nested classes. The static keyword refers to a class rather than a specific instance of that class. A constant variable or a […]

Garbage collection is the method through which Java programs maintain their memory automatically. working: Java programs are compiled into bytecode that may be executed by a Java Virtual Machine, or JVM. Objects are produced on the heap, which is a part of memory dedicated to the Java application, while it runs on the JVM. Some […]

this is a Java keyword that refers to the current object of a class. Uses of this keyword: The following are some examples of how to utilize this keyword: this can be used to refer to the current instance variable of a class. this can be used to call the method of the current class […]

In Java, there are numerous distinctions between method overloading and method overriding. The following is a list of the differences between method overloading and method overriding: No. Method Overloading Method Overriding 1) To make the program more readable, method overloading is used. Method overriding is used to provide a specific implementation of a method that […]

Polymorphism: Polymorphism is a Java concept that allows us to perform a single action in multiple ways. Polymorphism is made up of two Greek words: polymorphism and morphism. The words “poly” and “morphs” both mean “many.” Polymorphism denotes the presence of multiple forms. Types of polymorphism: compile-time polymorphism runtime polymorphism. Polymorphism in Java is achieved […]

In Java, method overriding occurs when a subclass (child class) has the same method as the parent class. Overriding is a feature that allows a subclass or child class to implement a method that is already provided by one of its super-classes or parent classes. When a subclass’s method has the same name, parameters, signature, […]

Method Overloading in Java: Method Overloading occurs when a class has multiple methods with the same name but different parameters. Compile-time (or static) polymorphism is linked to overloading. The readability of the program is improved by method overloading. We don’t have to develop new names for functions that do the same thing. Overloading the method […]

Association: Association is a relation between two separate classes which establishes through their Objects. One-to-one, one-to-many, many-to-one, and many-to-many associations are all possible. An Object communicates with another object to use its functionality and services in Object-Oriented programming. Composition and Aggregation are the two forms of association. Composition: The strongest type of association is composition. It represents part-of relationship. If […]

In Java, inheritance is a mechanism by which one object inherits all of its parent’s properties and behaviors. It is an essential component of OOPs (Object-Oriented programming systems). You can use the parent class’s methods and fields when you inherit from an existing class. You can also add new methods and fields to your current […]
