Write a class Route with the following features:
Constructor, which receives the length (floating-point number) and direction (direction-enum) as parameters.
Get and Set methods for length and direction.
import java.util.Random;
public class Test{
public static void main(String[] args){
final Random r = new Random();
System.out.println("Testing the class Route...");
double length = r.nextInt(200) + 10;
CardinalDirection direction = CardinalDirection.values()[r.nextInt(4)];
System.out.println("Creating with values (" + length + ", " + direction + ")");
Route r1 = new Route(length, direction);
System.out.println("Object created!");
System.out.println("Length: " + r1.getLength());
System.out.println("Direction: " + r1.getDirection());
System.out.println("Testing observation...");
for (int test = 1; test <= 3; test++) {
length = r.nextInt(200) + 10;
direction = CardinalDirection.values()[r.nextInt(4)];
System.out.println("Setting length to " + length);
r1.setLength(length);
System.out.println("Length: " + r1.getLength());
System.out.println("Setting direction to " + direction);
r1.setDirection(direction);
System.out.println("Direction: " + r1.getDirection());
}
}
}
//enum defined on the backend, in an earlier qn
//enum CardinalDirection {
// // north, south, east, west
// NORTH, SOUTH, EAST, WEST
//}
//ADD
class Route {
private double length;
private CardinalDirection direction;
//constructor
public Route(double length, CardinalDirection direction) {
this.length = length;
this.direction = direction;
}
public double getLength() {
return this.length;
}
public void setLength(double length) {
this.length = length;
}
public CardinalDirection getDirection() {
return this.direction;
}
public void setDirection(CardinalDirection direction) {
this.direction = direction;
}
}
Testing the class Route...
Creating with values (80.0, WEST)
Object created!
Length: 80.0
Direction: WEST
Testing observation...
Setting length to 189.0
Length: 189.0
Setting direction to SOUTH
Direction: SOUTH
Setting length to 155.0
Length: 155.0
Setting direction to SOUTH
Direction: SOUTH
Setting length to 24.0
Length: 24.0
Setting direction to WEST
Direction: WEST
