A class has four fields; temperature, min, max, and increment. They are all of int type. write a method to compare two class objects using equals method in Java. And if there is a method called setCooler in this class, how to execute this cooler method in different class that has main method. This is a basic java question, so, I am looking for basic answer to understand how things work. Finally, how to create insance fo previous class in main method and display temperature using getTemperature method in main method. Can somebody clearly explain this for me.
