Question

1) Write a method that will return the length of smallest string in an array of strings.
smallestLength ({“hola”, “word”, “night”, “boom”}) → 4
smallestLength ({“java”, “is”, “so”, “much”, “fun”}) → 2
smallestLength ({“i”, “love”, “java”}) → 1
//precondition: strs.length>0
public static int smallestLength(String[] strs)
{

}

Answer 1

public class Main
{
//precondition: strs.length>0
public static int smallestLength(String[] strs)
{
//returns length of the smallest string
int min=strs[0].length();
for(int i=0;i<strs.length;i++)
if(strs[i].length()<min)//updating min length, if current strings length is lesser
min=strs[i].length();
return min;
}
   public static void main(String[] args) {
   //testing above method
       System.out.println(smallestLength (new String[]{"hola", "word", "night", "boom"}));
       System.out.println(smallestLength (new String[]{"java", "is", "so", "much", "fun"}));
       System.out.println(smallestLength (new String[]{"i", "love", "java"}));
   }
}

output:
