    Default How to print each letter of string in reverse order in separate line?

    I'm having real trouble understanding this so apologies as I'm sure it's very basic! I think I've fixed the first couple of lines but struggling to understand how all these statements work. Can anyone see what this is supposed to be and how it should be written?

    public class Test { 
        public void main(String[] args){ 
           int i; for (i =0; i<10; i++){ 
               sum=sum+i; 
        if (i<j); 
        System.out.println(i); 
        else  
         System.out.println(j); 
        while(i<10); 
        { 
        j++; 
    };
    do{
        j++;
    }while(j<10) 
    }

    um... what is your program supposed to do? Without knowing that, it's very difficult to know how it is wrong.

    Also, please edit your post and put [code=java] [/code] tags around your code so that it might be readable.

    Have put the code round it, thanks didn't know that
    That's the problem though is that the challenge is to find out what is wrong and what it is supposed to do...
    The original code was:

    Public classTest { 
        Public void main(String[] args){ 
           for (int i =0;i<10;i++); 
               sum+=i; 
        if (i<j); 
        System.out.println(i); 
        else  
         System.out.println(j); 
        while(i<10); 
        { 
        j++; 
    };
    do{
        j++;
    }while(j<10) 
    }

    The so-called code is crap. (Sorry if that sounds harsh, but it is really, really, crap. Crap on a stick, wrapped in crap.) Besides the missing variables and syntax errors, the sequence is, simply, nonsense.

    You are telling us that you don't know what it is supposed to do? Where did you get the code? Found it under a cabbage leaf? The stork brought it? (That's a rhetorical question. I don't want an answer.)

    Does that sound too harsh? Well, since you are asking us what it is supposed to do, I am assuming that you didn't write it, so you shouldn't be offended. At least that's the way I see it.

    I can't imagine that looking at two dozen lines of nonsense can lead to understanding of the language or its applications. Can't you find some real code from a tutorial or a textbook or class notes (or something) to study?

    My recommendation: Get some "real" code. Compile it. Execute it. Study it. Make modifications and see if you can make sense out of the results.

    After studying whatever source material was available wherever you got the code, if there are parts that you don't understand, please post again and ask specific questions. There are lots of folks here who like to help (really) but we gotta have something to work with. Not c*** (Oh, great! Now the swear filter kicks in.)


    Cheers!
