need help to create this code

[Vineet.]

I need some help making some star patterns. The exact instructions are as follows:

Create separate programs to produce the following patterns:



I have to use for loops to get the patterns and I've already got (a.) but I can't seem to get the second. My first pattern's code is this:

a.)

int i,j;

for(i=4 ; i >= 1 ; i--){
for(j=1 ; j<=i ; j++)
System.out.print("*");
System.out.println();

If you can do it anyway you want, I would suggest using a for-loop.

It is actually quite easy, all you'd need is a loop that prints the string "*" x number of times. For example,

  // spoon fed solution deleted

Please don't spoon-feed solutions as that doesn't help the original poster learn to learn Java. Yes it's easier to answer this way, but they don't get the better understanding that occurs when they try to solve it first themselves first.

Next time, please at least show us what you've tried. This sort of post is nothing more than a homework dump and is not appreciated on this forum.

Alright, thanks for letting me know. I'm new to this forum, and giving java help, sorry.

Not to mention the solution didn't work.

Did it not? That's odd... Perhaps String.concat() is giving issues as it usually does.

[awinston]

Well for 1, String.concat() simply returns a new String with the argument at the end. The original String remains unchanged. In order to change the original String, you would have to do something like:

pat = pat.concat("*");

This works as well and it's easier for me:

pat += "*";

But the underlying problem with you solution is that it printed this:

*
**
***
****

which is the reverse of what OP is asking for.

Oh silly me, drop concat of course, I usually use += myself. Yeah, I just realized that it was backwards, but without spoonfeeding (I hope) wouldn't you just use -= on a string with * added x number of times?

Yeah, that sounds right!
