Java 打印连续数字倒直角三角形的程序

编写一个 Java 程序，使用 for 循环打印连续数字的倒直角三角形，并附带示例。

import java.util.Scanner;

public class InvertedRightTriConsec1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Inverted Right Triangle Consecutive Number Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Inverted Right Triangle of Consecutive Numbers Pattern");
		
		for (int i = rows ; i >= 1; i-- ) 
		{
			for (int j = 1 ; j <= i; j++ ) 	
			{
				System.out.print(j + " ");
			}
			System.out.println();
		}
	}
}

此 Java 示例 使用 while 循环显示连续数字的直角三角形。

import java.util.Scanner;

public class InvertedRightTriConsec2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Inverted Right Triangle Consecutive Number Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Inverted Right Triangle of Consecutive Numbers Pattern");
		int i = rows, j;
		
		while( i >= 1 ) 
		{
			j = 1 ;
			while ( j <= i ) 	
			{
				System.out.print(j + " ");
				j++;
			}
			System.out.println();
			i--;
		}
	}
}

Inverted Right Triangle Consecutive Number Pattern Rows = 9

Java 程序使用 do while 循环打印连续数字的倒直角三角形。

import java.util.Scanner;

public class InvertedRightTriConsec3 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Inverted Right Triangle Consecutive Number Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Inverted Right Triangle of Consecutive Numbers Pattern");
		int i = rows, j;
		
		do
		{
			j = 1 ;
			do 	
			{
				System.out.print(j + " ");

			}while ( ++j <= i );
			
			System.out.println();

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