Answer By True or False , JAVA LANGUAGE
A Java interface can contain only constants and abstract methods.
A class that implements an interface can define only the methods that are included in the interface.
A static variable can be referenced only from a static method.
Static variables are also called class variables.
Differentiate between abstract and concrete classes. Give examples from the scenario above

These values should be assigned to the object's instance variables: year and make. Accessor methods (getYear() and getMake()) that get the values of instance variables Mutator methods (setYear(int) and setMake(String)) that set the values of instance variables. toString() should return a string with the values of instance variables of vehicle object equals() should accept a vehicle object reference as argument and return true if all instance variables of calling object are same values as those of passed vehicle object, respectively, or false otherwise. brake() should do nothing (i.e., empty body).
