Program to Print Crown Number Pattern
In the previous article, we have discussed Java Program to Print Ladder Number Pattern
In this article we are going to see how to print crown number program.
When number of rows : 20 0 0 0 1 1 1 22 222 22 333 33333 333 4444 4444444 4444 55555 555555555 55555 66666666666666666666 77777777777777777777 88888888888888888888
Now, let’s see the actual program to print it.
If you are new to Java and want to learn the java coding skills too fast. Try practicing the core java programs with the help of the Java basic programs list available.
Approach to Print Crown Number Pattern
- Enter total row and store it in an integer variable
row. - Take height as h and
h=(row -1)/2. - Take first for loop to print the row value and number for each row .
- Take first inner for loop to print column value i.e., number according to condition
if (c == 0 || c == h || c == row – 1) and (r == h- 1)and
if ((c < r || c > h – r) &&(c < h + r || c >= row – r)) else print the spaces . - Then go on printing the numbers according to loop.
Java Code to Print Crown Number Pattern
import java.util.*;
public class Main
{
public static void main(String args[])
{
// taking variable for loop iteration and row .
int row,r,c,h;
//creating scanner class object
Scanner s = new Scanner(System.in);
// entering the number of row
System.out.print("Enter rows : ");
row = s.nextInt();
h= (row-1)/2;
for (r = 0; r < h ; r++)
{
// printing stars of the crown
for (c = 0; c < row; c++)
{
// for first row, print '*'
// i.e, for top part of crown
if (r == 0)
{
if (c == 0 || c == h || c == row - 1)
System.out.print(r);
else
System.out.print(" ");
}
else if (r == h- 1)
System.out.print(r);
else if ((c < r || c > h - r) &&(c < h + r || c >= row - r))
System.out.print(r);
else
System.out.print(" ");
}
// taking to the new line
System.out.println();
}
}
}
Output: Enter rows : 20 0 0 0 1 1 1 22 222 22 333 33333 333 4444 4444444 4444 555555 55555555 55555 66666666666666666666 77777777777777777777 88888888888888888888
