Question

Please use java language in an easy way and comment as much as you can! Thanks

1. (Write a code question) Write a generic method called "findMin" that takes an array of String objects as a parameter. (Use proper syntax, so that no type checking warnings are generated by the compiler.) The method should search the array and return the index of the smallest value.

Answer 1

public class StringOperation {
   public static void main(String[] args) {
       //input array
       String[] words = { "hello", "goodbye", "jack", "bye", "yes", "no", "yoo" };
       //printing results to console
   System.out.println("The shortest word is \"" + words[findMin(words)] + "\" at index "+findMin(words));
   }
//   a generic method called "findMin" that takes an array of String objects as a parameter.
   public static int findMin(String words[]) {
       //initilize the minString with 0 index
   String minString = words[0];
   int index = 0;
   //traversing array to find min length word
   for (int i = 1; i < words.length; i++) {
       //if found changeing minString with that founded string
   if (words[i].length() < minString.length()) {
       minString = words[i];
   index = i;
   }
   }
   // return the index of the smallest value.
   return index;
   }
}
