实现打印三角形

public class PrntTriangle{

    public static void main(String[] args) {

        int[] arr = {1,2,3,4,5,6,7,8,9,10};

        int line = 10;
        int index = 1;
        for(int x = 1; x < line; x++) {
            for(int y = 0; y < line - x; y++) {
                System.out.print(" ");
            }

            for(int z = 0; z < x; z++) {
                System.out.print((index++) + " ");
            }

            System.out.println();
        }
    }
}

结果
