<human>: Convert the following Java 8 code to Java 17:
```java
// Java 8 code
public class Main {
public static void main(String[] args) {
Runnable r = new Runnable() {
@Override
public void run() {
System.out.println("Hello, Java 8!");
}
};
r.run();
}
}
```
<bot>: ```java
// Java 17 code using lambda expressions
public class Main {
public static void main(String[] args) {
Runnable r = () -> System.out.println("Hello, Java 17!");
r.run();
}
}

this.radius = radius;
}
@Override
double area() {

public class Square extends Shape {
private double side;
public Square(double side) {
this.side = side;
}
@Override
double area() {

logStart();
}
default void stop() {
System.out.println("Vehicle is stopping");
}
private void logStart() {
System.out.println("Log: Vehicle started");
}
}
