Answer:
import java.util.Scanner;
public class Prahul {
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
int i,longleng=0,smal_leng=4, l , three_letter_word=0;
//longleng stores length of longest word
//smalleng stores length of shortest word
// l store the length of particular word
//three_letter_word stores the no of 3 letter word
String s,w="",lw="",sw="";
//lw stores longest word and sw stores smallest word
char c;
System.out.println("enter a sentence");
s=sc.nextLine().trim();
s=s+" ";
for(i=0;i<s.length();i++){
c=s.charAt(i);
if(c!= ' '){
w=w+c;
}
else{
l=w.length();
if(l==3){
three_letter_word++ ;
}
if(l>longleng){
longleng=l;
lw=w;
}
else if(l<=smal_leng) {
smal_leng = l;
sw = w;
}
w="";
}
}
System.out.println("longest word= "+ lw + " no of characters = " +longleng);
System.out.println("shortest word= "+sw+ " no of characters = " +smal_leng);
System.out.println("no of three letter word word= "+ three_letter_word);
}
}
