for loop in a for loop

[svush]

Hey! I've just started playing around with java programming, and i was wondering if someone could help me get this result with only the use of for loops?

Why would you need more than one loop?

 

Also, Java != JavaScript != Java.

Ok thanks for pointing out that im a newbeginner and that i put this in the wrong forum. Didnt help me much tho.

So you are trying to do it in Java then.

 

I can't help because I don't write Java, so I've moved it to the Java forum. I can tell you there is no reason you need more than one loop. Here's the PHP code:

 

<?php
for($i=0; $i<=9; $i++){
   if(!isset($string)){
        $string = "$i";
   }else{
   	$string = $i.$string;
   }
   echo $string.'<br>';
}
?>

 

PS: If this is homework, you need to learn to do it yourself. See the rules.

oki thx

Java would look something like:

String output = "";
for(int i=0; i{
   output = i + output;
   System.out.println(output);
}

I think maybe the point was to get you to look at how to control the flow of nested loops ...

 

public class Answer {
   public static void main(String argv[]) {
       for ( int start = 0; start <= 9; start++ ){
           System.out.printf("%d", start);
           for ( int inner = start-1; inner>=0; inner-- ){
               System.out.printf("%d", inner);
           }
           System.out.print("\n");
       }
   }
}

 

Jessica is right, you should try to do this for yourself, at the very least make sure you understand the answer, look for ways to improve it, perhaps find another way using a different control structure ...

 

Have fun
