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

Answer 1

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