Java 程序打印镜像菱形星形图案

编写一个 Java 程序，使用 for 循环打印镜像菱形星形图案。此镜像菱形图案示例使用嵌套的 for 循环来迭代菱形行。

package ShapePrograms;

import java.util.Scanner;

public class MirroredRhombus1 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Mirrored Rhombus Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Mirrored Rhombus Star Pattern");	

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

在此镜像菱形星形图案 程序中，我们用 while 循环替换了 for 循环。

package ShapePrograms;

import java.util.Scanner;

public class MirroredRhombus2 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Mirrored Rhombus Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Mirrored Rhombus Star Pattern");
		int j, k, i = 1 ;
		while( i <= rows ) 
		{
			j = 1 ;
			while (j < i ) 
			{
				System.out.print(" ");
				j++;
			}
			k = 1 ;
			while( k <= rows ) 
			{
				System.out.print("*");
				k++ ;
			}
			System.out.println();
			i++;
		}
	}
}

Enter Mirrored Rhombus Pattern Rows = 10

Java 程序使用 do while 循环打印镜像菱形星形图案

package ShapePrograms;

import java.util.Scanner;

public class MirroredRhombus3 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Mirrored Rhombus Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Mirrored Rhombus Star Pattern");
		int j, k, i = 1 ;
		do
		{
			j = 1 ;
			do
			{
				System.out.print(" ");
			} while (j++ < i );
			k = 1 ;
			do
			{
				System.out.print("*");
			} while( ++k <= rows );
			System.out.println();
		} while( ++i <= rows ) ;
	}
}

Enter Mirrored Rhombus Pattern Rows = 15

在此示例中，MirroredRhombusPat 函数打印给定符号的镜像菱形图案。

package ShapePrograms;

import java.util.Scanner;

public class MirroredRhombus4 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Mirrored Rhombus Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.print("Enter Character for Mirrored Rhombus Pattern = ");
		char ch = sc.next().charAt(0);
		
		MirroredRhombusPat(rows, ch);	
	}
	
	public static void MirroredRhombusPat(int rows, char ch) {
		for (int i = 1 ; i <= rows; i++ ) 
		{
			for (int j = 1 ; j < i; j++ ) 
			{
				System.out.print(" ");
			}
			for (int k = 1 ; k <= rows; k++ ) 
			{
				System.out.print(ch);
			}
			System.out.println();
		}
	}
}
