Question

/**
* q1: Write a public static method named q1 that takes an ArrayList of type String and
* returns an int. This method returns the *index of* the shortest String among the values
* of the input
*/

/**
* q2: Write a public static method named q2 that takes an ArrayList of Doubles as a
* parameter and returns an ArrayList of Doubles. The returned ArrayList will contain only
* the values from the input ArrayList that have a cube root within 2.0 of 3.04 (ie. the
* target value of the cube root is 3.04 and the allowed variance from this target is 2.0)

PLEASE USE JAVA.

Explanation / Answer

Java program to the given question:

import java.util.ArrayList;

public class Test
{
   public static void main(String[] args)
   {
       //array list of strings
       ArrayList<String> list= new ArrayList<String>();
      
       //adding strings to list
       list.add("Java");
       list.add("javascript");
       list.add("C#");
       list.add("Perl");
       list.add("C");
       list.add("HTML");
      
       //calling method q1() and assiging returning value to index variable
       int index=Test.q1(list);
       //displaying index
       System.out.print("index="+index);
   }

   //method implementation
   public static int q1(ArrayList<String> list)
   {
       //lets assume 1st index have string having small length
       int flen=list.get(0).length();
       int index=0;
      
       //loop to travese the list
       for(int i=0;i<list.size();i++)
       {
           //getting each string lenght in the arraylist
           int len=list.get(i).length();
           //comparing lenghts
           if(len<flen)
           {
               //if less then the current lenght
               index=i;
               flen=len;
           }
       }
      
       //returning index value to main method
       return index;
   }

}

Output: index=4
