Java ThreadLocal Variable Behavior

Question

What is the primary consequence of using a `ThreadLocal` variable for counter management in the multithreaded example shown below?

```java
public class ThreadLocalExample {
    private static ThreadLocal<Integer> threadLocalCounter = ThreadLocal.withInitial(() -> 0);
    
    public static void increment() {
        threadLocalCounter.set(threadLocalCounter.get() + 1);
    }
    
    public static int get() {
        return threadLocalCounter.get();
    }
}
```

Accepted Answer

Each thread maintains its own counter, so there is no shared aggregation across threads.

Answer

An exception is thrown because ThreadLocal cannot be used with numeric values.

Answer

A race condition occurs because each thread updates the same global counter simultaneously.

Answer

Deadlock happens when threads wait for access to the ThreadLocal variable.
