Thread safe, MT-safe: Use a mutex for every single resource to guarantee the thread to be free of race conditions when those resources are accessed by multiple threads simultaneously. Thread safety guarantees usually also include design steps to prevent or limit the risk of different forms of deadlocks , as well as optimizations to maximize ...
While a thread is executing a method of a thread-safe object, it is said to occupy the object, by holding its mutex (lock). Thread-safe objects are implemented to enforce that at each point in time, at most one thread may occupy the object. The lock, which is initially unlocked, is locked at the start of each public method, and is unlocked at ...
C# and Java are similar languages that are typed statically, strongly, and manifestly. Both are object-oriented, and designed with semi-interpretation or runtime just-in-time compilation, and both are curly brace languages, like C and C++.
C# provides the lock keyword on a thread to ensure its exclusive access to a resource. Visual Basic (.NET) provides a SyncLock keyword like C#'s lock keyword. Java provides the keyword synchronized to lock code blocks, methods or objects [11] and libraries featuring concurrency-safe data structures.

ThreadSafe detects Java concurrency defects: [2] [3] [4] Race conditions – which lead to incorrect or unpredictable behaviour that is difficult to reproduce in a debugger. Deadlocks [7] – caused by circular waits between threads waiting for shared resources.
Join-patterns provides a way to write concurrent, parallel and distributed computer programs by message passing.Compared to the use of threads and locks, this is a high level programming model using communication constructs model to abstract the complexity of concurrent environment and to allow scalability.
At least for Oracle/OpenJDK, this does not use native thread-local storage in spite of OS threads being used for other aspects of Java threading. Instead, each Thread object stores a (non-thread-safe) map of ThreadLocal objects to their values (as opposed to each ThreadLocal having a map of Thread objects to values and incurring a performance ...
