How to find the shortest string size in array of strings in Java

Answer 1

import java.util.Arrays;
  
public class MyClass {
    public static int shortest_string_size(String arr[]) {
        if (arr == null || arr.length < 1) {
            return -1;
        }
        int min = arr[0].length();
        int size = arr.length; 
        for (int i = 1; i < size; i++) {
            if (arr[i].length() < min) {
                min = arr[i].length();
            }
        }
        return min;
    }
    public static void main(String args[]) {
        String[] arr = {"java", "c#", "c++", "python", "php"}; 
  
        System.out.println(shortest_string_size(arr));
    }
}

import java.util.Arrays;
   
public class MyClass {
    public static void main(String args[]) {
        String[] arr = {"java", "c#", "c++", "python", "php"}; 
          
        String shortest_string = Arrays.asList(arr).stream()
                            .sorted((e2, e1) -> e1.length() < e2.length() ? 1 : -1)
                            .findFirst().get();
   
        System.out.println(shortest_string.length());
    }
}
