Absolute Java - Class: Heater

Create a class, Heater, that contains a single integer field, temperature. Define a constructor that takes no parameters. The temperature field should be set to the value 15 in the constructor. Define the mutators warmer and cooler, whose effect is to increase or decrease the value of temperature by 5 degree respectively. Define an accessor method to return the value of temperature.

 

public class Heater{private int temperature;public Heater(){ temperature = 15;}public void warmer(){temperature = temperature + 5;}public void cooler(){temperature = temperature - 5;}public int getTemperature(){return temperature;}//test: temperature(15)+5-5+5+5+5public static void main(String[] args) {Heater ht = new Heater();ht.warmer();ht.cooler();ht.warmer();ht.warmer();ht.warmer();System.out.println(ht.getTemperature());}}
