So, i created a method in a class called Lotion and I named it read() this method takes the user's input. I was told by my instructor that the method read() had to be private. However, he said that his demo/tester class should be able to access the method read(). He gave us a hint saying we had to use a constructor. But unfortunately, I still don't understand how it's supposed to work. Can Someone please explain.

Thanks in advance.

Your current code (as posted in comments)

private void read() {


     "Enter the amount of liquid in the bottle (0-100): ");

     volume = keyboard.nextDouble();

     if (volume > MAX || volume < MIN) { read(); } }


This initializes your object by setting volume.

You can call this from the class constructor:

  public Lotion(){



This way, when you create instances, it will automatically ask for user input and set the answer to an instance field.
