Thread: How to get rid of this?

Hello, so I am still stumped on this 99 bottles problem. I got most of it working however there are still some issues. This is what i have so far.

 public class BottleSong { 
 private int bottles = 0;
 
public BottleSong(int n)
 
{
 
    bottles = n;
 
 
 
 
 
}
 
public void printNumInEnglish(int n)
 
        {
 
 
 
           int tens = n/10;
 
            int ones = n%10;
 
            String t = new String();
 
            String o = new String();
 
 
 
 
 
            switch (tens)
 
            {
 
 
 
 
 
                case 1:
 
                    switch (ones)
 
                    {
 
                         case 0:
 
                              o = "Ten";
 
                            break;
 
                          case 1:
 
                              o = "Eleven";
 
                              break;
 
                         case 2:
 
                              o = "Twelve";
 
                              break;
 
                          case 3:

        BottleSong bs = new BottleSong(99);
 
        bs.printSong();
 
    }
 
 
 
}

When i run it, there are issues with the numbers past 20. It looks like:

twenty
Twenty bottles of beer on the wall,
Twenty bottles of beer,
Take one down, pass it around,
Twenty nineteen bottles of beer on the wall.

eighteen
Twenty nineteen bottles of beer on the wall,
Twenty nineteen bottles of beer,
Take one down, pass it around,
Twenty eighteen bottles of beer on the wall.

seventeen
Twenty eighteen bottles of beer on the wall,
Twenty eighteen bottles of beer,
Take one down, pass it around,
Twenty Seventeen bottles of beer on the wall.

sixteen
Twenty Seventeen bottles of beer on the wall,
Twenty Seventeen bottles of beer,
Take one down, pass it around,
Twenty Sixteen bottles of beer on the wall.

How do I get rid of the twenty in front of the teen numbers? If someone can help me with this that would be greatly appreciated.

Is this the same problem: http://www.javaprogrammingforums.com...html#post60690

Why not do this on the same thread instead of starting a new one?

No one knows the answer?

Where in the code is the lower case word printed? twenty
Where is the upper case word printed? Twenty

What does the uppercase word stay the same and the lower case one change?

Add some println statements to the code to print out all the variables used to compute the values that controls what is printed out. See why the uppercase word never changes and the lower case one does.

Can you please elaborate? What println statements and where should they go? Thank you.

Put a println at the beginning of each method and print out the arguments that are passed to.

Print out all the variables that you use to compute what is to be printed out.
Put the println right after the statement where their value is changed.
