Java 打印右递减数字的平方图案程序

编写一个 Java 程序，使用 for 循环打印右递减数字的平方图案。

package Shapes4;

import java.util.Scanner;

public class SquareRightDecNum1 {

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

这个 Java 程序 使用 while 循环打印右递减数字的平方图案。

package Shapes4;

import java.util.Scanner;

public class SquareRightDecNum2 {

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

Enter Square Right Decrement Numbers Rows = 8
