Java程序打印连续行字母的右三角形图案

编写一个Java程序，使用for循环打印连续行字母的右三角形图案。

package Alphabets;

import java.util.Scanner;

public class RightTriConsecRowAlp1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Consec Row Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Consecutive Row Alphabets Pattern");
		int alphabet = 64;
		
		for (int i = 1; i <= rows; i++) 
		{
			int val = i;
			for (int j = 1; j <= i; j++ ) 	
			{
				System.out.print((char)(alphabet+ val) + " ");
				val = val + rows - j;
			}
			System.out.println();
		}
	}
}

这个Java模式示例使用while循环显示每行连续字母的直角三角形。

package Alphabets;

import java.util.Scanner;

public class RightTriConsecRowAlp2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Consecutive Row Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Consecutive Row Alphabets Pattern");
		int alphabet = 64;
		int val, j, i = 1; 
		
		while (i <= rows) 
		{
			val = i;
			j = 1;
			
			while( j <= i ) 	
			{
				System.out.print((char)(alphabet+ val) + " ");
				val = val + rows - j;
				j++;
			}
			System.out.println();
			i++;
		}
	}
}

Enter Right Triangle of Consecutive Row Alphabets Rows = 8

这个Java程序使用do while循环来显示连续行字母的直角三角形图案。

package Alphabets;

import java.util.Scanner;

public class RightTriConsecRowAlp3 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Right Triangle of Consecutive Row Alphabets Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Right Triangle of Consecutive Row Alphabets Pattern");
		int alphabet = 64;
		int val, j, i = 1; 
		
		do
		{
			val = i;
			j = 1;
			
			do	
			{
				System.out.print((char)(alphabet+ val) + " ");
				val = val + rows - j;

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

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