Write Nested Loop For Pyramid Pattern

Write a nested loop for a pyramid pattern. Well here's an ugly description of what it should look like:

1
1 2 1
1 2 4 2 1
1 2 4 8 4 2 1
1 2 4 8 16 8 4 2 1
1 2 4 8 16 32 16 8 4 2 1
1 2 4 8 16 32 64 32 16 8 4 2 1
1 2 4 8 16 32 128 64 32 16 8 4 2 1

I managed to make the pyramid using addition. However, how to turn it into multiplication x 2.

import java.util.*;

public class NumbersPyramid
{
public static void main(String[] args) {
int odd = 1;
int numSpaces = 7;

[code]....
