1. Suppose making a class called Day. Two of its variables are year and currentTemperature.

The step is

Year should be a final variable, and currentTemperature should not be final.

Can you explain why?

2. When we write a unit test only basing the test on the documentation, which tells us what the function is supposed to do, this is an example of a: Black Box Test

Can you explain!

Assuming working on a project that involves programming a simulation of a game of soccer. The current step in the project is to implement kicking the ball. These students all follow the recommended order for designing and testing code. Look at the following code that the students just finished writing to decide which of the following students is closest to completing this step?

The code is below. Please explain.

/** Kick checks if the player can kick the ball, and if yes, kicks the ball
*
* @param b A ball object to kick
* @returns false if they cannot kick, otherwise true
*/
public boolean kick(Ball b) {
  double d = distance(this.getLocation(), b.getLocation());
  // people need to be closer than 1 distance to kick the ball
  if (d < 1.0) {
//get vector of kick
    Vector v = getVector(this.getLocation(), b.getLocation());
    newLocation = b.getLocation() + v * this.kickForce;
    b.setLocation(newLocation);
} else {
    return false;
  }
}
