/*Define a Student class (roll: integer, number: string,
marks: float). Define no argument and parameterized getter
methods for initializing student object. Create two student objects.
One object is initialized using parameterized getter method and
second one is initialized using no-argument getter methods. Also
print the contents of each object using display() method. (Use of
method overloading)*/
