Java Forum / First Aid / March 2008nested for loops
Hi all, I'm new to java and google groups alike. I needed some help on creating the following out put. 1 22 333 4444 55555 666666 7777777 88888888 999999999 I've seen it done in class but can't seem to remember. There were only two for loops in the code. Can someone help me with the code? > Hi all, I'm new to java and google groups alike. I needed some help > on creating the following out put.

For a homework assignment, help here will be very limited.

This new concept was introduced yesterday Friday and I didn't have a good grasp on it. I wanted to use this weekend to stare at the code and learn how it works. I've already finished all currently assigned programming projects for the class. This is more a desire to stay ahead and not fall behind. My brain doesn't quite understand this nested for loops easily and felt it necessary to familiarize myself. > My brain doesn't quite understand this nested for loops >easily and felt it necessary to familiarize myself. Do you understand for loops? If not read up on them. They are covered in every introductory text, including free online ones. Do you understand a for loop that calls a method? Do you understand a method that calls a for loop? If you understand yes to both questions you can nest? Do you understand how to encapsulate/unravel a method? If yes, then you can nest for loops. Just don't look at the whole thing. look at each loop as for ( stuff ) { body }; Close your eyes for the moment than the body may be yet another for loop. It is a problem very much like factoring in algebra. You have to close your eyes to detail not currently relevant. -- Roedy Green Canadian Mind Products The Java Glossary http://mindprod.com nosmadadivad wrote: > Hi all, I'm new to java and google groups alike.

Can someone help me with the code? For the code to be executable there must have been more than two for loops. public class Print { public static void main(String[] args) { for( ... ) { for( ... ) { System.out.print(); } System.out.println(); } } } > nosmadadivad wrote: > > Hi all, I'm new to java and google groups alike.

You're right... clairification - I needed to know what the code is within the for (THIS CODE){ for(THIS CODE){ .. anyways I googled it and the code came up. Thanks for your responses. Off to study I go..... I needed to know what the code is within the for (THIS CODE){ for(THIS CODE){ .. anyways I googled it and the code came up. Thanks for your responses. Off to study I go..... Yup,congrats,you're welcome,bye. >Hi all, I'm new to java and google groups alike.

You need to call THAT repeatedly. So that leaves two problems: 1. how many times. 2. how long each time. Tackle them separately. -- Roedy Green Canadian Mind Products The Java Glossary http://mindprod.com >999999999 > >I've seen it done in class but can't seem to remember. There were >only two for loops in the code. Can someone help me with the code? solve the problem of how to create just that row of 9s first. Then figure out how to display an list of any digit. Then build your triangle. You need only the simplest for loop.
