java金字塔问题如何解决

import java.util.Scanner;
public class towel{
public static void main(String args[]){
System.out.println("请先输入金字塔的高度h：");
    Scanner sc=new Scanner(System.in);
    int n=sc.nextInt(); 
    int no=0;   
    int x=0;
    int y=0;
for(x=1;x<=n;x++){
  for(no=n-x;no>0;no--){
    System.out.println(" ");
}
    for(y=1;y<=(x-1)*2+1;y++){
        System.out.print("*"); 
}
System.out.println();
}  
}
}

上面是我的代码，我想输出金字塔，但是每一行都是从左边开始，怎么从中间开始

每行前面加空格啊

        System.out.println("请先输入金字塔的高度h：");
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        int no = 0;
        int x = 0;
        int y = 0;
        for (x = 1; x <= n; x++) {
            for (no = n - x; no > 0; no--) {
                System.out.print(" ");
            }
            for (y = 1; y <= (x - 1) * 2 + 1; y++) {
                System.out.print("*");
            }
            System.out.println();
        }
    }
}
