What is the importance of Garbage Collection in Java

Garbage Collection (GC) in Java is a crucial process that automatically removes unreferenced objects from memory, enabling efficient memory management. This process helps prevent memory leaks, optimizes the memory usage of Java applications, and is vital for long-running applications, ensuring they don’t consume more memory than necessary over time.

Java's garbage collector works in the background to identify and dispose of objects that are no longer in use. This allows developers to focus on the logic of their applications without worrying about manual memory management. The main benefits of garbage collection include improved performance, optimized resource consumption, and simplified programming.

In general, garbage collection contributes to system stability and improves the longevity of applications by handling memory management tasks. Java incorporates several garbage collection algorithms (like the Serial GC, Parallel GC, CMS, and G1), allowing developers to choose the one that best fits their application needs.

// Example of how garbage collection can be triggered in Java public class GarbageCollectionExample { public static void main(String[] args) { // Creating a large number of objects for (int i = 0; i < 100000; i++) { String temp = new String("Temporary String " + i); } // Suggesting JVM to run Garbage Collector System.gc(); System.out.println("Garbage Collection suggested."); } }
