How to find the length of the shortest word in a string with Java

Answer 1

public class Program {
    public static void main(String args[]) {
        String s = "Java is object oriented programming language";    
        String[] words = s.split(" ");
 
        int shorLength = words[0].length();

        for (int i = 1; i < words.length; i++) {
            if (words[i].length() < shorLength) {
                shorLength = words[i].length();
            }
        }
        System.out.println(shorLength);
    }
}

public class ShortestWord {

    // Returns the length of the shortest word in the string
    public static int shortestWordLength(String text) {
        if (text == null || text.isEmpty()) {
            return 0;
        }

        // Split on whitespace (spaces, tabs, newlines)
        String[] words = text.trim().split("\\s+");

        int minLen = Integer.MAX_VALUE;

        for (String word : words) {
            int len = word.length();
            if (len < minLen) {
                minLen = len;
            }
        }

        return minLen == Integer.MAX_VALUE ? 0 : minLen;
    }

    public static void main(String[] args) {
        String text = "Find the shortest word length in this string";

        int result = shortestWordLength(text);

        System.out.println("Shortest word length: " + result);
    }
}

  
  
/*
run:
  
Shortest word length: 2
  
*/
