Question #348663

Create an interface called StudentInterface. This interface has the following abstract method:

public void study(String subject);

The Student class implements this interface, and provides an implementation for study() which displays that the student is studying a certain subject.

(Note what happens if you don’t implement study().)

interface StudentInterface {
    void study(String subject);
}

class Student implements StudentInterface {
    // If `study` method is not implemented, then a compilation error happens
    public void study(String subject) {
        System.out.println("The student is studying " + subject);
    }
}

class Test {
    public static void main(String[] args) {
        Student student = new Student();
        student.study("Math");
    }
}
