Java wait Method Synchronization Context

Question

What is the primary issue with the use of the `wait()` method in the code segment below?

```java
public class WaitExample {
    private boolean condition = false;
    
    public void doWait() {
        if(!condition) {
            try {
                wait();
            } catch (InterruptedException e) {
                Thread.currentThread().interrupt();
            }
        }
    }
    
    public void setConditionTrue() {
        condition = true;
    }
    
    public static void main(String[] args) {
        WaitExample we = new WaitExample();
        new Thread(() -> we.doWait()).start();
    }
}
```

Accepted Answer

Calling wait() outside of a synchronized context will throw an IllegalMonitorStateException at runtime.

Answer

There is no issue because wait() can be invoked within any method as long as it's conditionally called.

Answer

The if statement should be replaced by a while loop to avoid spurious wakeups, which is the primary error.

Answer

The wait() method is incorrectly placed; it should be called only after the condition becomes true.
