Java 程序打印递减顺序的倒直角三角形数字

编写一个 Java 程序，使用 for 循环打印递减顺序的倒直角三角形数字。

import java.util.Scanner;

public class InvertedRightTriDecreasing1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Inverted Right Triangle of Descreasing Numbers Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Inverted Right Triangle of Numbers in Reverse Order");
		
		for (int i = rows ; i >= 1; i-- ) 
		{
			for (int j = i ; j >= 1; j-- ) 	
			{
				System.out.print(j + " ");
			}
			System.out.println();
		}
	}
}

此Java 示例使用 while 循环打印递减顺序的倒直角三角形整数数字模式。

import java.util.Scanner;

public class InvertedRightTriDecreasing2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Inverted Right Triangle of Descreasing Numbers Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Inverted Right Triangle of Numbers in Reverse Order");
		int j, i = rows ;
		
		while (i >= 1 ) 
		{
			j = i ;
			while(j >= 1 ) 	
			{
				System.out.print(j + " ");
				j--;
			}
			System.out.println();
			i--;
		}
	}
}

Inverted Right Triangle of Descreasing Numbers Rows = 8
Inverted Right Triangle of Numbers in Reverse Order
8 7 6 5 4 3 2 1 
7 6 5 4 3 2 1 
6 5 4 3 2 1 
5 4 3 2 1 
4 3 2 1 
3 2 1 
2 1

使用 do while 循环打印递减顺序倒直角三角形数字的 Java 程序。

import java.util.Scanner;

public class InvertedRightTriDecreasing3 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Inverted Right Triangle of Descreasing Numbers Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Inverted Right Triangle of Numbers in Reverse Order");
		int j, i = rows ;
		
		do
		{
			j = i ;
			do 	
			{
				System.out.print(j + " ");

			} while(--j >= 1 );
			
			System.out.println();

		} while (--i >= 1 );
	}
}
