StudentTest.java

{

    public static void main(String[] args) throws InterruptedException
    {
        Student johnReferenceVariable = getStudent("John", 25);

        System.out.println("Name : " + johnReferenceVariable.getName());
        System.out.println("Age  : " + johnReferenceVariable.getAge());

        System.out.println("--------------------------------");

        Student peterReferenceVariable = getStudent("Peter", 55);

        System.out.println("Name : " + peterReferenceVariable.getName());
        System.out.println("Age  : " + peterReferenceVariable.getAge());

    }

    /*
     * Returning a Class:
     * 
     * When a method uses a class name as its return type, the class of the type
     * of the returned object must be either a subclass of, or the exact class
     * of, the return type.
     */
    public static Student getStudent(String name, int age)
    {
        Student student = new Student();
        student.setName(name);
        student.setAge(age);
        return student;
    }

}

Name : John
Age  : 25
--------------------------------
Name : Peter
