打印镜像数字三角形图案的Java程序

编写一个Java程序，使用for循环打印镜像数字的三角形图案。

package Shapes3;

import java.util.Scanner;

public class TriangleMirroredNum1 {

private static Scanner sc;

public static void main(String\[\] args) {
	sc = new Scanner(System.in);
	
	System.out.print("Enter Traingle Mirrored Numbers Rows = ");
	int rows = sc.nextInt();
	
	System.out.println("Printing Traingle of Mirrored Numbers Pattern");
	
	for (int i = 1; i <= rows; i++ ) 
	{
		for (int j = rows; j > i; j-- ) 
		{
			System.out.print(" ");
		}
		for(int k = 1; k <= i; k++) 
		{
			System.out.print(k);
		}
		for(int l = i - 1; l >= 1; l--)
		{
			System.out.print(l);
		}
		System.out.println();
	}
}

这个Java模式的例子使用while循环打印镜像数字的三角形。

package Shapes3.X

import java.util.Scanner;

public class TriangleMirroredNum2 {

private static Scanner sc;

public static void main(String\[\] args) {
	sc = new Scanner(System.in);
	
	System.out.print("Enter Traingle Mirrored Numbers Rows = ");
	int rows = sc.nextInt();
	
	System.out.println("Printing Traingle of Mirrored Numbers Pattern");
	int j, k, l, i = 1;
	
	while(i <= rows) 
	{
		j = rows;
		while(j > i) 
		{
			System.out.print(" ");
			j--;
		}
		
		k = 1; 
		while(k <= i) 
		{
			System.out.print(k);
			k++;
		}
		
		l = i - 1;
		while(l >= 1)
		{
			System.out.print(l);
			l--;
		}
		
		System.out.println();
		i++;
	}
}

Enter Traingle Mirrored Numbers Rows = 9
