Question

2. Consider an ADT list of integers. Write a method public int computeMin (IntegerListinterface alist) that computes and returns the minimum of the integers in the given list alist or returns Integer.MAX VALUE if the given list is empty For example, if aList- <70, 65, 98, 94>, your method should return 65. Note: 1) Your method should work for any list of integers. 2) The definition of your method should be independent of the list's implementation (ie. your method should not depend on whether the list is array-based or reference-based or based on some other data structure).

Answer 1

Solution:

public int computeMin(List<Integer> alist){
  
if (alist.size()==0 || alist == null) //checking whether list is empty or contains a null value
return Integer.MAX_VALUE;
  
List<Integer> sortlist = new ArrayList<>();
sortlist=alist;
Collections.sort(sortlist); //sorting the list

return sortlist.get(0); //after sorting the minimum element will be at index 0
}
