Solution:

class printDiamond

{

public static void main(String abc[])

{

int Diamond_Size=19;      

if(Diamond_Size%2==1)

{

printUpperTriangle(Diamond_Size);

System.out.println();

printLowerTriangle(Diamond_Size);

}

else

{

System.out.println("Please set limit to some odd number");

}
}

public static void printUpperTriangle(int limit)

{

int sp=limit/2;

for(int i=1,space=sp;i<=limit;i+=2,space--)

{

if(space>=0)

{

printSpace(space);

for(int j=1;j<=i;j++)

{

System.out.print("*");

}

}

System.out.println();

}

}

public static void printLowerTriangle(int limit)

{

int sp=limit/2;

for(int i=limit-2,space=1;i>0;i-=2,space++)

{

if(space<=sp)

{

printSpace(space);

for(int j=1;j<=i;j++)

{

System.out.print("*");

}

}

System.out.println();
}

}

public static void printSpace(int space)

{

for(int i=space;i>0;i--)
{

System.out.print(" ");

}

}

}

//[Note: Grow Diamond size by increasing value of Diamond_Size variable.

//for example Diamond_Size=29; 

//please set Diamond_Size variable to odd numbers only.]
