Java 打印倒星形金字塔程序

编写一个 Java 程序，使用 for 循环打印倒星形金字塔模式。此倒金字塔模式示例使用嵌套的 for 循环来迭代和显示输出。

package ShapePrograms;

import java.util.Scanner;

public class InvertedPyramid1 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Inverted Pyramid Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Inverted Pyramid Star Pattern");
		
		for (int i = rows ; i >= 1; i-- ) 
		{
			for (int j = 0 ; j < rows - i; j++ ) 
			{
				System.out.print(" ");
			}
			for (int k = 0 ; k != (2 * i) - 1; k++ ) 
			{
				System.out.print("*");
			}
			System.out.println();
		}
	}
}

在此倒星形金字塔程序中，我们将 for 循环 替换为 while 循环。

package ShapePrograms;

import java.util.Scanner;

public class InvertedPyramid2 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Inverted Pyramid Pattern Rows = ");
		int rows = sc.nextInt();
		

		int i = rows, j, k ;
		while ( i >= 1) 
		{
			j = 0 ;
			while (j < rows - i ) 
			{
				System.out.print(" ");
				j++;
			}
			k = 0 ;
			while ( k != (2 * i) - 1) 
			{
				System.out.print("*");
				k++ ;
			}
			System.out.println();
			i-- ;
		}
	}
}

Enter Inverted Pyramid Pattern Rows = 10

使用 do while 循环打印倒星形金字塔的 Java 程序

package ShapePrograms;

import java.util.Scanner;

public class InvertedPyramid3 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Inverted Pyramid Pattern Rows = ");
		int rows = sc.nextInt();
		

		int i = rows, j, k ;
		
		do
		{
			j = 0 ;
			do
			{
				System.out.print(" ");
			} while (j++ < rows - i );
			k = 0 ;
			do
			{
				System.out.print("*");
			} while ( ++k != (2 * i) - 1);
			System.out.println();
		} while ( --i >= 1) ;
	}
}

Enter Inverted Pyramid Pattern Rows = 13

在此示例中，InvertedPyramidPattern 函数打印给定符号的倒金字塔模式。

package ShapePrograms;

import java.util.Scanner;

public class InvertedPyramid4 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Inverted Pyramid Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.print("Character for Inverted  Pyramid Pattern = ");
		char ch = sc.next().charAt(0);
		

		InvertedPyramidPattern(rows, ch);		
	}
	
	public static void InvertedPyramidPattern(int rows, char ch) {
		for (int i = rows ; i >= 1; i-- ) 
		{
			for (int j = 0 ; j < rows - i; j++ ) 
			{
				System.out.print(" ");
			}
			for (int k = 0 ; k != (2 * i) - 1; k++ ) 
			{
				System.out.print(ch);
			}
			System.out.println();
		}
	}
}

Enter Inverted Pyramid Pattern Rows = 16
Character for Inverted  Pyramid Pattern = $
