java螺旋填數三角形,Java使用嵌套循環列印數字三角形

I am trying to print the following using a nested loop in Java:

1 2 3 4 5 6

1 2 3 4 5

1 2 3 4

1 2 3

1 2

1

but it's coming out like the following:

1 2 3 4 5 6

2 3 4 5 6

3 4 5 6

4 5 6

5 6

6

Here is my code:

for (int i = 1; i <= 6; i++) {

for (int j = 1; j < i; j++)

{

System.out.print(" ");

}

for (int j = i; j <= 6; j++)

{

System.out.print(j + " ");

}

System.out.println();

}

Any help would be appreciated. Thanks

解決方案int n = 7;

for (int i = 1; i <= n; i++) {

for (int j = 1; j < i; j++) {

System.out.println(" ");

}

for (int j = i; j <= 6; j++) {

System.out.println(j +" ");

}

}
