How does Java handle memory management?

[IT Education center]

In Java, memory management is handled automatically by the Java Virtual Machine (JVM). The JVM is responsible for allocating and deallocating memory for objects.

Java uses a garbage collector mechanism to automatically reclaim memory that is no longer in use. The garbage collector runs in the background and identifies objects that are no longer reachable by the program. These objects are considered garbage and are eligible for garbage collection.

When an object is no longer referenced by any part of the program, the garbage collector frees up the memory occupied by that object. This process is known as automatic memory management or garbage collection.

Java's garbage collector uses different algorithms such as Mark and Sweep, Copying, and Generational to handle memory management efficiently. The algorithms determine the approach for identifying and collecting garbage objects.

One advantage of Java's automatic memory management is that it relieves the developer from explicitly deallocating memory. This helps prevent memory leaks, which can occur in languages that require manual memory management.

However, it's important for developers to be aware of their program's memory usage and avoid creating unnecessary objects that may increase memory consumption.
