Question

Create a java class called Fan to represent a fan. The class contains:

Three constants named SLOW, MEDIUM, and FAST with the values 1, 2, and 3 to denote the fan speed.
A private int data field named speed that specifies the speed of the fan (the default is SLOW).
A private boolean data field named on that specifies whether the fan is on (the default is false).
A private double data field named radius that specifies the radius of the fan (the default is 5).
A string data field named color that specifies the color of the fan (the default is blue).
The accessor and mutator methods for all four data fields.
A no-arg constructor that creates a default fan.
A method named toString() that returns a string description for the fan. If the fan is on, the method returns the fan speed, color, and radius in one combined string. If the fan is not on, the method returns the fan color and radius along with the string "fan is off" in one combined string.

Then create a test program called TestFan that creates two Fan objects. For the first Fan object, assign maximum speed, radius 10, color yellow, and turn it on. For the second Fan object, assign medium speed, radius 5, color blue, and turn it off. Display the objects by invoking their toString() method.

Explanation / Answer

class FanStoreTest {

static Fan[] fans = new Fan[2];
static final int S_L_O_W = 1;
static final int MED = 2;
static final int HAULS_BUTT = 3;

public static void main( String[] args ) {

fans[0] = new Fan( HAULS_BUTT, 10.0, "yellow", true);
fans[1] = new Fan();

fans[1].setSpeed( MED );

for( int i = 0; i<fans.length; i++ ) {
System.out.println( fans[ i ].toString() );
}
}
}
