How Does Java’s Memory Model Affect Multithreading?

Java’s memory model defines how variables are read and written in a multithreaded environment.

Visibility and Atomicity

It ensures visibility of variables between threads and atomicity of operations.

Example Code

            class SharedResource {
                private int counter = 0;
                public synchronized void increment() {
                    counter++;
                }
                public int getCounter() {
                    return counter;
                }
            }
            

This example demonstrates synchronization to ensure proper memory visibility in multithreading.
