Java 程序打印左移数字的平方图案

编写一个Java程序，使用for循环打印左移数字的平方图案。

package Shapes4;

import java.util.Scanner;

public class SquareLeftShiftNum1 {

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

这是打印左移数字平方图案的Java程序的另一种写法。

package Shapes4;

import java.util.Scanner;

public class SquareLeftShiftNum2 {

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

Enter Square Left Shift Numbers Rows = 16

2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 1

8 9 10 11 12 13 14 15 16 1 2 3 4 5 6 7 
9 10 11 12 13 14 15 16 1 2 3 4 5 6 7 8 
10 11 12 13 14 15 16 1 2 3 4 5 6 7 8 9

14 15 16 1 2 3 4 5 6 7 8 9 10 11 12 13 
15 16 1 2 3 4 5 6 7 8 9 10 11 12 13 14 
16 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 

这个Java示例使用while循环从上到下显示左移数字的平方图案。

package Shapes4;

import java.util.Scanner;

public class SquareLeftShiftNum3 {

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