Answer
import java.util.Scanner;

{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.println("Enter a sentence:");
String str = in.nextLine();
int wCount = 0, lCount = 0;
int len = str.length();
for (int i = 0; i < len; i++) {
char ch = str.charAt(i);
if (ch == ' ')
wCount++;
else
lCount++;
}
/*
* Number of words in a sentence are one more than
* the number of spaces so incrementing wCount by 1
*/
wCount++;
System.out.println("No. of words = " + wCount);
System.out.println("No. of letters = " + lCount);
}
}
