is this your homework ?
try it first by yourself, if you got problems, send us your codes to this
mailing list.
This homework is not difficult to solve ... :)

just a hint, learn about looping in Java ..

This is a simple programming problem. Look into mod (MODUDLUS) operations,
and use mod 10. (Should be Math.mod - checkout the Math class).

Here is the code for that:

class NumberTriangle
{
public static void main(String[] args)
{
int i, j=0, k=0;
while(k<=15){
for(i=0;i<=k;i++)
{
System.out.print(" ");
}
for(i=0;i<=15-k;i++)
{
System.out.print(j+" ");
}
System.out.println();
k++;
j++;
if(j>9)
j=0;
}
}

}

As a university "Intro to Computer Science" instructor, I believe that you
just did someone's homework for them. I can only hope that they learn
enought to be able to create this code correctly on the midterm in a couple
of weeks.

as a student you shouldnt ask... and if you do and dont understand
the answer, you shouldnt pass ... life is selfregulating, thats my firm
belief

I dont know if you are one of the "help me get a triangle  output" guys...
if not i dont think my comment regards you. ;o)

I dont know how university works in other parts of the world, but being a
university student myself in sweden I have seen that there is a lot of
tutoring going on... and that this rather than the lecture is what will
teach us programming...

Programming is that kind of subject that (like for instance mathematics)
wont go in undless you write code-write code-write code... hehehe...

Well, so when i see people comming here asking how to print out a triangle
i can only assume they (and their college?) are in deep deep trouble...
ehhh... okay maybe harsh but... we cannot be the instructors for a
university... maybe we should start a java-uni list on here and send all
triangles there? (and maybe with some persuasion we may get the uni
instructors to join it as well? ;o)

But surely, you people with the triangles... don't you have tutoring?
