Can someone explain to me why I keep getting a syntax error on this else statement?

remove the semicolon from line 21 after if statement.


Life is easy because we write the source code.....

So is the problem with line number 9 i.e. remove the semicolon

No. That won't cause a compilation error.
But as an advance notice to the OP. When you run your program and it just sits there doing nothing, the problem is the semi colon on line 9

no error is on line no 21 only..........check the program.......

because else should immediately follow the nearly if statement..otherwise it gives compilation eror......


if you remove line no 22,23,24,25....then your code will also compile fine....

John,

Here's a little tip to help you get better help around here. When you ask a question like "why do I get a compiler error?" it is of unimaginable help for you to provide the exact text of the compiler error. What the compiler outputs will tell you a LOT about what your problem is, but in particular the exact line where the problem is.

In your case, you say there is an issue with your if statement...and then there are TWO if statements. So now, if someone wants to help you, they have to figure out where the error is...and some people won't bother taking the time.

Your job is to make it as easy as possible for someone to help you.

If you would have provided this:

C:\slop>javac ninety_nine_bottle.java
ninety_nine_bottle.java:26: 'else' without 'if'
else

we would know the exact problem is on line 26, that the IF block was closed somehow, and we'd know immediatly to look at the IF on line 21 instead of the IF on line 11.


There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
