Java Program to find the largest and smallest word in a string.

public class SmallestLargestWord    
   
  public static void main(String[] args){     
      String string = "Hardships often prepare ordinary people for an extraordinary destiny";    
      String word = "", small = "", large="";    
      String[] words = new String[100];    
      int length = 0;    
          
      //Add extra space after string to get the last word in the given string    
      string = string + " ";    
          
      for(int i = 0; i < string.length(); i++){    
          //Split the string into words    
          if(string.charAt(i) != ' '){    
              word = word + string.charAt(i);    
          }    
          else{    
              //Add word to array words    
              words[length] = word;    
              //Increment length    
              length++;    
              //Make word an empty string    
              word = "";    
          }    
      }            
      //Initialize small and large with first word in the string    
      small = large = words[0];    
          
      //Determine smallest and largest word in the string    
      for(int k = 0; k < length; k++){    
              
          //If length of small is greater than any word present in the string    
          //Store value of word into small    
          if(small.length() > words[k].length())    
              small = words[k];    
   
          //If length of large is less than any word present in the string    
          //Store value of word into large    
          if(large.length() < words[k].length())    
              large = words[k];    
      }    
      System.out.println("Smallest word: " + small);    
      System.out.println("Largest word: " + large);    
  }  }  

Output:

Smallest word: an
Largest word: extraordinary
