Two threads.
One shared variable.
And suddenly `count++` becomes dangerous. 😄
That's why Java has `synchronized`.
It helps control access to shared data and provides memory-visibility guarantees.
Simple examples 👇

Simple examples 👇
@xojo.comWhen several threads need access to the same file, database, or other resource, what synchronization approach do you use? Xojo’s Semaphore class supports both waiting for access with Signal and checking immediately with TrySignal.

@gaurav1403.bsky.socialYou submitted a `Callable` task.
Now you need its result. 🤔
That's where `Future` comes in:
```java
Future<Integer> f =
executor.submit(() -> 10 + 20);
Integer result = f.get();
```
I explained Future, CompletableFuture
@gaurav1403.bsky.social`Runnable` can do the work.
But what if the thread needs to **return a result**? 🤔
That's where `Callable` comes in.
I explained Callable, Future, exceptions, ExecutorService and real examples in my latest ByteCraft article.
@gaurav1403.bsky.socialWant to create a thread in Java without extending `Thread`?
I explained it simply in my latest ByteCraft article.
@gaurav1403.bsky.social`t.start()` ≠ `t.run()`
`start()` → schedules a new thread
`run()` → normal method call
Java multithreading gets interesting when you add scheduling, shared data, synchronization and thread pools.
