aving some problems taking in the Java at Uni,

Was wondering if anyone could shine some light on it for me.

My task is to write a program that will ask you to enter 2 words. the program will then print out both words on one line. However the words will be seperated by dots that will make the total length of the line 40. so if your first word was turtle and the second was abc, the output would be

turtle...............................abc

The program should check for certain conditions:

1. a word can not be longer than 37 characters;
2. there must always be atlest 2 dots in a line.

The program should ask for the first word till a word of acceptable length is entered. it then does the same for the second word.

once both words are input the prgram will either output an error message if the words are to long when combined;

or output the required line with words.

I have to write the program using while and/or do-while loops

It also says something about the length of a string can be found out using myString.length().

I can understand the basic of what I need to do but with regards to word length and adding the required number of dots im fooked.

Any pointers would be appreciated.

Cheers.

I don't do Java, so bear with me on this one.
In another life (it seems) there once was a programming language named Cobol. I used to do some coding in that.
The logic shouldn't be much different,though. Check the first word and determine its length. Check the second word length. Total the two lengths. Add the first word to the output line, then a string of periods as determined by a for / while loop based on the sum of the word lengths and the length of the output line. Finally, the second word. Might think about using an array to store all that in, too.
As stated above, I don't have the foggiest idea of the specifics of Java for this code, but that logic should work.
Is this what you needed?

yes, basically your string_var.length() is going to be the boundary for the loop, if you can use 'for' loops instead. I haven't written Java programs for over a year now, but it'll be something like this:

[CODE]
int total_word_length = string1.length() + string2.length();
system.out.print(string1); //*darn*, don't remember the syntax here
for ( int i=word_length; i<40; i++)
{
system.out.print( "." );
}
system.out.print(string2);

(PS, this was written just before me falling to sleep and could be very wrong... in that case, sorry )

Usually for input where not everything is acceptable, you use a while(true) loop, then if what the user enters is acceptable, you break, otherwise go back to the beginning. Since you have two things, use two while(true)s. Something like this:

Of course you can self-study. What else do we have internet tutorials for... I have done this with several languages with great success.
