A diamond should be like this:
*
* *
* *
* *
*
I want to use simple for loop for it can somebody help? I have tried a complete diamond:
void main() throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.println("ENTER THE HEIGHT ");
int ht = Integer.parseInt(br.readLine());
int ht2 = (int) Math.floor(ht / 2);
ht = (int) Math.ceil(ht / 2);
for (int ht3 = ht - 1; ht3 >= 0; ht3--) {
for (int i = 1; i <= ht3; i++)
System.out.print(" ");
for (int j = 1; j <= ht - ht3; j++)
System.out.print("* ");
System.out.println();
}
for (int ht3 = 1; ht3 <= ht2; ht3++) {
for (int i = 1; i <= ht3; i++)
System.out.print(" ");
for (int j = ht2 - ht3; j >= 1; j--)
System.out.print("* ");
System.out.println();
}
}
import java.io.*;
public class EmptyDiamond {
void main() throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.println("ENTER THE HEIGHT ");
int ht = Integer.parseInt(br.readLine());
int space = ht - 1;
int midspace = -1;
int k;
for (int c = 1; c <= Math.ceil(ht / 2); ) {
for (int i = space; i >= 1; i -= 2) {
int i2 = i;
while (i2 != 0) {
System.out.print(" ");
i2--;
}
System.out.print("*");
for (int j = 1; j <= midspace; j++)
System.out.print(" ");
if (c != 1)
System.out.print("*");
midspace += 4;
System.out.println();
c++;
}
}
for (int c = 1; c <= Math.floor(ht / 2); ) {
for (int i = 0; i <= space; i += 2) {
int i2 = i;
while (i2 != 0) {
System.out.print(" ");
i2--;
}
midspace -= 4;
System.out.print("*");
for (k = midspace + 4; k >= 1; k--)
System.out.print(" ");
if ((c != (ht / 2 + 1)))
System.out.print("*");
System.out.println();
c++;
}
}
}
}
