Parse Value Of Array Of Object Passed Through A Parameter

I'm working on a method that would parse the value of the array of object that I passed through a parameter. I would like to ask if making Object as a parameter is doable. Let's say I have a class Student and Teacher. I created a class the would handle the sched and name it class Schedule and extend this class to the Student and Teacher. Now I want to have a function that will accept an array of Schedule from either Student and Teacher, what ever object I will pass in the parameter. I know its easy to just make a method with a separate parameter of my classes but im looking for a more dynamic code.

class Student extends Schedule{
//variables here for student
}
[code]

class Teacher extends Schedule{
//variables here for teacher
}
[/code]

private void parseObject(ArrayList<Object> objct){
Schedule temp = objct.get(0);
//there is no error in this part

}

Now when i will try to use the function and pass a data, it will not accept since my parameter should be an array of object. How would I twist dis one?

ArrayList<Student> temp_student = new Array....
parseObject(temp_student); // it will not accept my parameter, how would i make it as an object
