In the Spring Framework, a "bean" is an object that is instantiated, assembled, and managed by the Spring IoC (Inversion of Control) container. The scope of a bean defines the lifecycle and visibility of that bean within...
In Java, a deep copy refers to the process of creating a new object that is a copy of an existing object, along with all the objects referenced by it. This means that not only the original object is duplicated, but also ...
Java is often described as a "pure" object-oriented programming (OOP) language, but this characterization can be somewhat nuanced. To understand why Java is considered pure in the context of OOP, we need to explore the p...
In Java, "fail fast" and "fail safe" are two concepts related to how collections and other data structures handle concurrent modifications and errors. They are particularly relevant in the context of iterating over colle...
In Java, "fail-safe" and "fail-fast" are terms that describe how a system or a collection behaves when it encounters an error or an unexpected condition. They are particularly relevant in the context of concurrent progra...
In Java, a daemon thread is a type of thread that runs in the background to perform tasks that do not prevent the program from exiting. Daemon threads are typically used for background tasks such as garbage collectio...
In Java, a daemon thread is a type of thread that runs in the background to perform tasks that do not prevent the program from exiting. Daemon threads are typically used for background tasks that support the main app...
The Spring Framework is a powerful and widely-used framework for building Java applications. It provides a comprehensive programming and configuration model that is suitable for modern Java-based enterprise applications....
The Spring Framework is a powerful and widely-used framework for building Java applications, particularly in enterprise environments. Here are some of the key benefits of using the Spring Framework from the perspective o...
Constructor chaining in Java is a technique where one constructor calls another constructor in the same class or in a superclass. This allows for code reuse and can help to avoid redundancy when initializing objects. Con...
In Java, you can remove duplicates from a list using various methods. Below are examples for both List<Stringand List<Item. You can use a Set to remove d...
Java is a widely-used programming language known for its versatility and robustness. Here are some of its key features: Object-Oriented: Java is based on the principles of object-oriented programming (OOP), which...
Java design patterns are typically categorized into three main types: Creational, Structural, and Behavioral patterns. Each category serves a different purpose in software design and architecture. Here’s a brief overview...
In Java, objects become eligible for garbage collection (GC) when there are no more references to them, meaning that they can no longer be accessed or used by the program. Here are some common ways to make objects eligib...
In Java, the concepts of shallow copy and deep copy refer to the ways in which objects can be duplicated. Understanding these concepts is important for managing object references and ensuring that changes to one object d...
A Just-In-Time (JIT) compiler is a component of runtime environments that improves the performance of programs by compiling code at runtime rather than before execution. It is commonly used in environments like Java Virt...
Let's dive deeper into instance variables and local variables in Java, covering their definitions, characteristics, scope, lifecycle, default values, and providing code examples for clarity.
In Java, memory management is crucial for efficient program execution, and it is divided into two main areas: Heap and Stack memory. Each serves different purposes and has distinct characteristics. Below are the key diff...
In Java, memory management is crucial for efficient program execution, and it is divided into two main areas: Heap and Stack memory. Here are the key differences between Heap and Stack memory:
In Java, final methods and abstract methods serve different purposes and have distinct characteristics. Here’s a breakdown of the differences between them: Definition: A final method is a ...
In Java, the term "final" can be used as a modifier for variables, methods, and classes, but it specifically refers to the immutability of a variable when applied to a variable. When a variable is declared as final, it...
In Java, the final keyword can be applied to classes, methods, and variables, and it serves different purposes in each context. When a class is declared as final, it means that the class cannot be subclassed or exten...
In Java, the final keyword can be applied to classes, methods, and variables, and it serves different purposes in each context. When it comes to methods, declaring a method as final means that the method cannot be ov...
In Java, the final keyword is used to declare constants or to restrict the modification of variables, methods, and classes. When a variable is declared as final, it means that once it has been assigned a value, it ca...
