Thread: Working code But not intended result?

Hello, again, I have another question if your able to help me. I am doing the Stanford 106a class on you tube so I am using acm imports which are outdated apparently but any help none the less would be appreciated.

I am trying to write a program that will type out the song 99 bottles of beer on the wall counting all the way down to 0 where I declare I am drunk. The problem I am having is that when it runs what ever the user inputs as the value they want to start with it wont count backwards it will just use that number however many times it prints out(what ever is declared to start).

I hope that explanation is good enough! Trying to be short sorry if not clear.Here is my code:

 
		public void run() {
			println("This program will sing the dreaded song 99 bottles of beer on the wall");
			println("Feel free to change 99 to what ever you see fit");
			int nBottles = readInt("Enter the perfered # of bottles you would like to start with");
			println(+nBottles+"bottles of beer on the wall,");
			for(int i=nBottles;i>0;i--) {
				println(+nBottles+"bottles of beer on the wall");
				println	(+nBottles+"bottles of beer.");
				println	("you take one down and pass it around.");
 
 
			}
 
 
			println("now I drunk am...oh shit I got my mixed all words up and ");
			println("I don't undermean what I stand...hiccup");

The variable nBottles is the one printed out but it doesn't change, it just prints that same number over until done instead of subtracting a number each time which is what I would like it to do. I think I am close, very tough trouble shooting myself though, the one bad side of self learning I guess.

well I was looking for honest feed back not wise ass remarks, I am new to this like I said so no I didn't answer my own question, if I did I wouldn't know it(hence being new! HMMMM)

The post also only involved one variable and I only asked about one, I got it to work with out the for loop

This is what I ended up using..

 
		public void run() {
			println("This program will sing the dreaded song 99 bottles of beer on the wall");
			println("Feel free to change 99 to what ever you see fit");
			int nBottles = readInt("Enter the perfered # of bottles you would like to start with");
			println(+nBottles+" bottles of beer on the wall"+nBottles+" bottles of beer.");
			println("you take on down and pass it around");
			nBottles--;
 
			while(nBottles>0) {
				println(+nBottles+" bottles of beer on the wall.");
				println(+nBottles+" bottles of beer on the wall,"+nBottles+" bottles of beer.");
				println("you take one down and pass it around,");
				nBottles--;
			}
 
 
			println("now I drunk am...oh shit I got my mixed all words up and ");
			println("I don't undermean what I stand...hiccup");
 
 
		}

Is it possible for me to have done that program with a for loop?
To me this almost made sense but I am struggling with 4 loops for some reason.

I see it does basically the same thing, I just don't understand why it wouldn't work for me with a for loop .So if I wrote it correctly it should still work with the for loop?
Gonna have to try to practice

--- Update ---

I just got it to work with the for loop!! I just rearranged a few println's and added nBottles-- to inside the statement of the for loop.

I do thank you Junky, I was grumpy just coming home from work and I found your post insulting to me is all, I realize your intentions and the fact that your on here helping ppl speaks for itself. thanks again and sry!
