class Words

{

    String str1,str2,maxs,mins;

    int max,min;

    BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

       private void show() throws Exception

      {

         System.out.print("\nEnter the sentence:");

         str1=br.readLine().trim();

         str1=str1+" ";

         max=0;

         min=str1.length();

         while(true)

         {

              int i=str1.indexOf(' ');

              if (i<0 o:p="">

              break;

              str2=str1.substring(0,i);

              str1=str1.substring(i+1);

              if(str2.length()>max)

              {

                   max=str2.length();

                   maxs=str2;

                }

                else if(str2.length()

              {

                   min=str2.length();

                   mins=str2;

                }

            }

            System.out.println("Longest Word Is:"+maxs);

            System.out.println("Shortest Word Is:"+mins);

               

        

}

      

        public static void main(String args[]) throws Exception

        {
