Need help analysising for loop

[djtoxicdance]

im having a tough time understanding the for loop in this code and what the limits of the loop are. I need help breaking the code down and understanding a for loop.
[CODE]class Diamond {
public static void main(String[] args) {
for (int i = 1; i < 10; i += 2) {
for (int j = 0; j < 9 - i / 2; j++)
System.out.print(" ");

for (int j = 0; j < i; j++)
System.out.print("*");

System.out.print("\n");
}

for (int i = 7; i > 0; i -= 2) {
for (int j = 0; j < 9 - i / 2; j++)
System.out.print(" ");

for (int j = 0; j < i; j++)
System.out.print("*");

System.out.print("\n");
}
}
}

What is your question? exactly what is it you are stuck on or don't understand?

I don’t understand the code. You see what i posted for the code was given to us in class. i was told to learn how the code works and how to change it so you get different shapes. Like to how to change it from a diamond to just a triangle. But i don’t understand how the for loop works and what its limits are. Because i figured out that to get a triangle all i need is a for loop with different limits.

Add System.out.println for both of the loop variables ( 'i' and 'j' ). Seeing how they change will help you understand the loops and see exactly how each of the loops exits.
