Newbie having problems with for loop

[Dannii]

Greetings to all,

I have an assignment to do but I do not yet fully understand how to display the correct data in a for loop.
The assignment is this:
1. Let the user write 10 words, each separated with ENTER/Return key
2. Display each word the other way around. Meaning display the last written word first!

This is the code I have made but the for loop aint working. It only shows the int 9 8 7 6 5 4 3 2 1 and not the words written.
Any ideas and suggestions would be appreciated.

import java.io.*;
import java.util.*;
public class uppg3 {
	public static void main (String[] args) throws IOException {
		BufferedReader input = new BufferedReader (new InputStreamReader(System.in));
		System.out.println("Write 10 words"); 
			
		int rows = 0, words=0;
		while (rows <10){
		System.out.print("Ord"+(rows+1)+"? ");
   		String s = input.readLine();
   		if (s==null)
        break;
      	rows++;
      	StringTokenizer t = new StringTokenizer(s);
      	words = words + t.countTokens();
   				
		}
		for (int i=9; i>=0; i--){
			System.out.println(words);
		}
}

I am aware that this assignment can be done with array however its not allowed =)

a few things.
First off are you required to use BufferedReader and StringTokenizer? You can accomplish the same thing easier using

//declare 10 string variables
Scanner in = new Scanner(System.in);
word1 = in.nextLine();
word2 = in.nextLine();
...
word10 = in.nextLine();

and then just print the words out with a simple print statement.

//edit
Sorry I misread the part about having to use a for loop. disregard this for the most part.

word is an int. you want to print the text which is s in your code.

Also you can't compare strings using "==" you have to use the String method equals():

if (s.equals(null))

I hope the above will work.

Why don't you just modify a buffer string?

Something like

    public String revers() throws IOException {
        BufferedReader input = new BufferedReader (new InputStreamReader(System.in));
        String buffer = "";
        String inputString = "";
        for (int i = 0; i <= 10; i++) {
            inputString = input.readLine();
            if(inputString != null)
                buffer = inputString + " " + buffer;
        }
        return buffer;
    }

Also you can't compare strings using "==" you have to use the String method equals():

Though in most cases this is true, I'm pretty sure that the "==" operand compares the reference. So if s references a null object it "s == null" should return true. If your comparing two strings it's best to use a deep comparison (String.equals).
