Answer 1

You can use Scanner or BufferedReader to read info from file. Store it in an arrayList and then use Collections.sort() on the arrayList.
Also you can store it in an array and use an sorting algorithm like selection sort or quick sort.
If you have many details like the name, dob, etc, you probably have to store each attribute in its own array and then you can sort based on any attribute.
