Java provides support for multithreading, but it also comes with challenges related to data visibility and ordering of operations. The Java Memory Model (JMM) defines rules and guarantees for how threads interact with memory, ensuring a level of consistency. The basics of memory consistency involve concepts like atomicity, visibility, and ordering of operations. In Java, synchronization mechanisms like synchronized methods/blocks and the java.util.concurrent package can be used to control access to shared resources and ensure memory consistency. Developers can also use practical tips like employing volatile, using thread-safe collections, and utilizing atomic classes for atomic operations to manage memory consistency effectively. ## Full article daily.dev links to this article rather than hosting it.
