Garbage Collection Algorithm: G1 (Garbage First) GC The G1 GC (Garbage First Garbage Collector) is the default garbage collector in the HotSpot JVM (Java 9+). It is designed for low pause times and efficient memory management, especially for large heaps … Continue reading →

Types of Garbage Collectors in the HotSpot JVM The HotSpot JVM (Java Virtual Machine) implements multiple Garbage Collectors (GCs) to manage memory efficiently. Each GC has different strategies optimized for various workloads.

The Garbage Collector (GC) in Java is responsible for automatically managing memory by reclaiming objects that are no longer reachable. It helps prevent memory leaks and optimizes memory usage without requiring manual memory management (unlike C or C++).

What is the assert Statement Used For in Java? The assert statement in Java is used for debugging and testing by checking assumptions in the code. It helps identify logic errors during development.

Features of Using Nested Classes in Java: Static and Non-Static (Internal) Nested classes in Java help organize code, improve encapsulation, and reduce unnecessary dependencies. Java provides two main types of nested classes: Static Nested Classes (declared with static) Non-Static Nested … Continue reading →

What is a “Static Class” in Java? In Java, a class cannot be declared as static at the top level. However, a nested class (a class inside another class) can be static. This is called a static nested class. Top-Level … Continue reading →

Java provides several types of classes to support different programming needs. Here’s a breakdown of the major types:
