<human>: Convert the following Java 8 interface with default methods to Java 17 using private interface methods:

```java
// Java 8 code
public interface Vehicle {
  default void start() {
    System.out.println("Vehicle is starting");
    logStart();
  }
  default void stop() {
    System.out.println("Vehicle is stopping");
  }
  private void logStart() {
    System.out.println("Log: Vehicle started");
  }
}
```

<bot>: ```java
// Java 17 private methods in interfaces
public interface Vehicle {
  default void start() {
    System.out.println("Vehicle is starting");
    logStart();
  }
  default void stop() {
    System.out.println("Vehicle is stopping");
  }
  private void logStart() {
    System.out.println("Log: Vehicle started");
  }
}
```
