Another solution is to put the question and inside a Map typed ArrayList. In such way, it will create a key-value pairs(key-question, value-answer) each item inside the arraylist. then later after moving to the next page of the exam(assuming its a multipage) or on clicking the next button or submit button, insert everything to the db by iterating each map item.
Why use array or map or a list? what if along the course, magbago ang isip ni examinee? binago nya yung sagot nya(nagiba ng click sa radiobutton) tapos ang approach mo is insert the answer every click of radiobutton, e di magkakaron ng redundancy sa answer for each question.
