Java 打印连续数字直角三角形行程序

编写一个 Java 程序，使用 for 循环打印直角三角形的连续行号。

import java.util.Scanner;

public class ConsecutiveNumberinrows1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Consecutive Row Numbers Right Triangle Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Consecutive Row Numbers Right Triangle Pattern");

		for (int i = 1 ; i <= rows; i++ ) 
		{
			int val = i;
			
			for (int j = 1 ; j <= i; j++ ) 	
			{
				System.out.print(val + " ");
				val = val + rows - j;
			}
			System.out.println();
		}
	}
}

使用 while 循环的 Java 连续行号直角三角形 程序。

import java.util.Scanner;

public class ConsecutiveNumberinrows2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Consecutive Row Numbers Right Triangle Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Consecutive Row Numbers Right Triangle Pattern");
		int val, j, i = 1 ; 

		while(i <= rows) 
		{
			val = i;
			j = 1 ;
			
			while( j <= i ) 	
			{
				System.out.print(val + " ");
				val = val + rows - j;
				j++;
			}
			System.out.println();
			i++;
		}
	}
}

使用 do while 循环打印连续数字直角三角形行的 Java 程序。

import java.util.Scanner;

public class ConsecutiveNumberinrows3 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Consecutive Row Numbers Right Triangle Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Consecutive Row Numbers Right Triangle Pattern");
		int val, j, i = 1 ; 

		do
		{
			val = i;
			j = 1 ;
			
			do	
			{
				System.out.print(val + " ");
				val = val + rows - j;

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

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