To create a new project , heater-exercise with a new class Heater and declare a single variable temperature of type double . The value of the variable temperature is set to 15.0 using the constructor. Two methods , warmer() and cooler() are used to change the temperature by 5.0 degrees. An accessor method , getTemperature ( ) is also used. Program Plan: Write a program in BlueJ to create a new class Heater. In the class, a single variable temperature of type double is used. The value for the field temperature is set to 15.0 using the constructor. The method warmer() increases the temperature by 5 degrees and cooler() decreases the temperature by 5 degrees. The method getTemperature() is used to return the value of the temperature.
