编写一个Java程序,使用for循环打印反向镜像的直角三角形星形图案。这个Java反向镜像直角三角形例子根据If条件打印星形或空位。
package ShapePrograms;
import java.util.Scanner;
public class RevMirroredRightTri1 { private static Scanner sc;
public static void main(String\[\] args) {
sc = new Scanner(System.in);
System.out.print("Enter Reverse Mirrored Right Triangle Rows = ");
int rows = sc.nextInt();
System.out.println("Reverse Mirrored Right Triangle Star Pattern");
for (int i = 1 ; i <= rows; i++ )
{
for (int j = 1 ; j <= rows; j++ )
{
if(j < i)
{
System.out.print(" ");
}
else
{
System.out.print("\*");
}
}
System.out.println();
}
}
在这个Java反向镜像的右三角星形图案程序中,我们用while循环代替了for循环。
package ShapePrograms;
import java.util.Scanner;
public class RevMirroredRightTri2 { private static Scanner sc;
public static void main(String\[\] args) {
sc = new Scanner(System.in);
System.out.print("Enter Reverse Mirrored Right Triangle Rows = ");
int rows = sc.nextInt();
int i = 1, j;
while( i <= rows )
{
j = 1 ;
while(j <= rows)
{
if(j < i)
{
System.out.print(" ");
}
else
{
System.out.print("\*");
}
j++;
}
System.out.println();
i++;
}
}
Enter Reverse Mirrored Right Triangle Rows = 10

使用do while循环打印反向镜像右三角星形图案的Java程序
package ShapePrograms;
import java.util.Scanner;
public class RevMirroredRightTri3 { private static Scanner sc;
public static void main(String\[\] args) {
sc = new Scanner(System.in);
System.out.print("Enter Reverse Mirrored Right Triangle Rows = ");
int rows = sc.nextInt();
int i = 1, j;
do
{
j = 1 ;
do
{
if(j < i)
{
System.out.print(" ");
}
else
{
System.out.print("\*");
}
} while(++j <= rows);
System.out.println();
} while( ++i <= rows );
}
Enter Reverse Mirrored Right Triangle Rows = 14

在这个Java例子中,RevMirroredRightTriangle函数打印了一个给定符号的反向镜像右三角形图案。
package ShapePrograms;
import java.util.Scanner;
public class RevMirroredRightTri4 { private static Scanner sc;
public static void main(String\[\] args) {
sc = new Scanner(System.in);
System.out.print("Enter Reverse Mirrored Right Triangle Rows = ");
int rows = sc.nextInt();
System.out.print("Character for Reverse Mirrored Right Triangle Pattern = ");
char ch = sc.next().charAt(0);
RevMirroredRightTriangle(rows, ch);
}
public static void RevMirroredRightTriangle(int rows, char ch) {
for (int i = 1 ; i <= rows; i++ )
{
for (int j = 1 ; j <= rows; j++ )
{
if(j < i)
{
System.out.print(" ");
}
else
{
System.out.print(ch);
}
}
System.out.println();
}
}
Enter Reverse Mirrored Right Triangle Rows = 17
Character for Reverse Mirrored Right Triangle Pattern = #
