A: The examples below uses three classes, VariableHost, VariableCaller and VariableSubclass, all in the same default package for simplicity. The VariableHost class has a static class variable and an instance variable and the cases show how they are accessed from the host class itself and the other classes.

public class VariableHost {

  static int staticInt = 2;

  int instanceInt = 4;

  public static void main(String[] args) {

    // Static reference
    int staticAccess = staticInt;

    // Object reference necessary for instance variable
    VariableHost hostInstance = new VariableHost();

    int instanceAccess = hostInstance.instanceInt;
  }
}
