Java程序打印反向倒直角三角形数字

编写一个Java程序，使用for循环打印反向的倒直角三角形数字图案。

import java.util.Scanner;

public class InvertedRightTriReverse1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Inverted Right Triangle Reverse Numbers Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Inverted Right Triangle of Numbers in Reverse Order");
		
		for (int i = 1 ; i <= rows; i++ ) 
		{
			for (int j = rows ; j >= i; j-- ) 	
			{
				System.out.print(j + " ");
			}
			System.out.println();
		}
	}
}

此Java程序使用while循环显示反向的倒直角三角形图案，其中每列的数字相同。

import java.util.Scanner;

public class InvertedRightTriReverse2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Inverted Right Triangle Reverse Numbers Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Inverted Right Triangle of Numbers in Reverse Order");
		
		int i = 1, j;
		
		while (i <= rows ) 
		{
			j = rows ; 
			while (j >= i ) 	
			{
				System.out.print(j + " ");
				j--;
			}
			
			System.out.println();
			i++;
		}
	}
}

Inverted Right Triangle Reverse Numbers Pattern Rows = 7
Inverted Right Triangle of Numbers in Reverse Order
7 6 5 4 3 2 1 
7 6 5 4 3 2 
7 6 5 4 3 
7 6 5 4 
7 6 5 
7 6 
7 

Java程序使用do while循环打印反向的倒直角三角形数字。

import java.util.Scanner;

public class InvertedRightTriReverse3 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Inverted Right Triangle Reverse Numbers Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Inverted Right Triangle of Numbers in Reverse Order");
		
		int i = 1, j;
		
		do
		{
			j = rows ; 
			do 	
			{
				System.out.print(j + " ");

			} while (--j >= i );
			
			System.out.println();

		} while (++i <= rows );
	}
}
