Creating a Pattern Assignment

[NoviceJava]

Hey,

I'm having trouble with an assignment and I need some help.

basically, the assignment is the same as the from the following link:
http://www.thescripts.com/forum/thread607498.html

However, there is one major exception: The pattern is reversed. Here is what it looks like:
If the user types "3", your program should produce the following output:
***
**
*
If the user types "9", your program should produce:
*********
********
*******
******
*****
****
***
**
*

I found out how to do the other pattern of my own but I am having trouble figuring out how to flip it.

Here is my code so far:
------------------------------------------------------------------
import java.io.*;

public class MagicPrinter
{
public static void main(String[] args)
throws java.io.IOException
{
String s1, s2, s3, total;
int num, minnum;
char a = 'a';
String star = "*";

total = "";

InputStreamReader isr = new InputStreamReader(System.in);

BufferedReader br = new BufferedReader(isr);

System.out.print("How many lines? ");
s1 = br.readLine();
num = Integer.parseInt(s1);

minnum = 1;

do
{
total = total + star;
minnum++;

System.out.println(total);
}
while(minnum <= num);
}
}
----------------------------------------------------------------

Any help would be apprecitated. Thanks.

Algorithm:

Assuming my input is 7

while( input not equal to 0 )
 
       Print the ' * ' input times...
       Create new line...
       Decrement the input...

I tried this and it is giving me the output

*
*
*
*
*
*
*
*

This is what I typed:
while (num != 0)
{
System.out.println(star);
num--;
}

when I also try:
while (num !=0)
{
total = total + star;
System.out.println(total);
num--;
}

I get the same pattern I had to begin with. Maybe I'm just unsure of what you meant by print '*' input times...

print '*' input times is = Print the asterisk many times depend on the input, if my input is currently 7, then print the asterisk 7 times in the same line...

Maybe you forgot this,

What is the difference between

System.out.print("Something");

and

System.out.println("Something");

If you can differentiate that, then proceed... If you are not sure, make some experiments about the two...

I know the difference between the methods; println returns a new line after completing while print prints subsequent information on the same line. I played around with many different things and this is what I ended with

while (num != 0)
{
total = total + star;
System.out.print(total);
System.out.print("");
num--;
}

When imputing 9 I get the required number of stars but on the same line. When i use println for the second method I just get the same result I had to begin with.

You must understand the code below before you attempt to try it, if you don't follow my instructions, later you will be dependent from the others....

I hope you will understand this....

public class demo{
    public static void main(String sukatoa[]){
        int input = new java.util.Scanner(System.in).nextInt();
        while(input > 0){
            System.out.println();
            for(int x=0;x<input;x++){
                System.out.print("*");
            }input--;
        }System.out.println();
    }
}

The code i've posted above will be deleted after a few minutes by the moderator... Please, read the book carefully next time...

Try to make have some experiments... Later you will come-up an idea...

Thank You. I now see. So first comes the space and then the input, along with the corresponding amount of stars. The input is then decreased by one and a new line is then printed whereby the decreased amount of stars follows the same process until it reaches 1. At least I think I've now got it.

Nice flow...

No probz.. ;-)
