Diamond pattern in Java

Java program to print diamond pattern

We are going to create a pattern that looks like a diamond, somewhat resembling the diamonds we find in a deck of playing cards. The aforesaid has to be created out of any character given as input.

The basic idea is to first print a Pascal Triangle out of input character and then print an inverted Pascal Triangle as a continuation below it.

Source Code:

/* Program to print Diamond*/
import java.util.*;
class Diamond
{
public static void main()
{
Scanner inp=new Scanner(System.in);
System.out.print("\n Enter Any Character: ");
char c=((inp.nextLine()).charAt(0));
System.out.print("\n Enter Size Limit: ");
int n=inp.nextInt();
int i,j,x=(n-1);
System.out.println("Diamond: \n");

for(i=1;i<=n;i++) { for(j=1;j<=x;j++) System.out.print(" "); x--; for(j=1;j<=(2*i)-1;j++) { System.out.print(c); } System.out.println(); } x=1;

for(i=1;i<=(n-1);i++) { for(j=1;j<=x;j++) System.out.print(" "); x++; for(j=1;j<=2*(n-i);j++) System.out.print(c);

System.out.println(); }

} }

Output:

Enter Any Character: #

Enter Size Limit: 5 Diamond:

#

####### ######### #######

#

Enter Any Character: &

Enter Size Limit: 4 Diamond:

& &&& &&&&& &&&&&&& &&&&& &&& &
