Hi friend,

Code to help solve the problem :

import java.util.*;
public class Diamond
{
static Scanner console=new Scanner(System.in);
public static void main(String[]args)
{
int noOfstarlines;
int counter;
System.out.println("Enter the number of star lines");
noOfstarlines=console.nextInt();
for(counter=1;counter<=noOfstarlines;counter++)
{
printStars(counter);
}
}

public static void printStars(int size)
{
int i,j,k,l,m,n;
System.out.println("size " +size);

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

}
}

Thanks
