I don't even know how to start it...
thank you for any help or comments!

Answer 1

Search for the data: based on its name?email?
perform a loop and end the loop when it reaches the last data

when it finds the data, use the data's array number
for(int i=0; i<studentList.size(); i++){
student = (Student) studentList.get(i);

if ( student.getName().equalsIgnoreCase(searchedName){
//assign to the object here
found = true;
}
}

this is to update the data

if you want to remove the data be sure to decrement the array size after delete

I only remember completing tasks using data structure and I forgot about some java basics which is pretty bad
