Code:
import java.util.Scanner;public class Pattern8
{
public static void main( String args[])
{
System.out.print("Enter the number of rows:");
Scanner sc=new Scanner(System.in);
int n=sc.nextInt();
int ck=0,c=2;
while(c>0)
{
if(ck == 0)
{
for(int i = 1;i <= n ; i++)
{
for(int j =1 ; j <= i ; j++)
{
System.out.print(j);
}
System.out.println();
}
ck++;
}
else
{
for(int i =1 , r = n-1 ; i <= n - 1 ; i++ ,r--)
{
for(int j = 1 ; j <= r; j++)
{
System.out.print(j);
}
System.out.println();
}
}
c--;
}
sc.close();
}
