How can i create these shapes with java

Question

package assignment.pkg3;

import java.util.Scanner;

public class Assignment3 {

  public static void main(String[] args) {
    Scanner stdIn = new Scanner(System.in);
    System.out.print("What integer length do you want: ");
    int length = stdIn.nextInt();

    for (int i = 0; i < length; i++) {
      for (int j = ((length - 1) - i); j > 0; j--) {
        System.out.print(" ");
      }
      for (int a = 0; a <= i; a++) {
        System.out.print("*");
      }
      System.out.println();
    }

    for (int i = 0; i < length; i++) {
      for (int j = 0; j < i; j++) {
        System.out.print(" ");
      }
      for (int a = length; a > i; a--) {
        System.out.print("*");
      }
      for (int b = (length - 1); b > i; b--) {
        System.out.print("*");
      }
      System.out.println();
    }

    for (int i = 0; i < length; i++) {
      for (int j = 0; j <= i; j++) {
        for (int k = 0; k < i; k++) {
          System.out.print(" ");
        }
        for (int a = 0; a <= i; a++) {
          System.out.print("*");
        }
        System.out.println();
      }
    }
  }
}

Hi, I need help making this 3rd shape.. I don't even know how to start it. I did the other 3 pretty well. (except I have the spaces wrong on shape D). Can anyone help me find somewhere to start. (BTW I'm in a beginner java class so I can't put anything in there that we haven't learned. So sticking to for loops is basically all we can essentially use lol) Here is link to pic

Try to execute this one & check -

for (int i = 0; i < length/2; i++){

            for (int j = 0; j < length; j++){
                System.out.print("*" + " ");
            }
            System.out.println("");

            for (int k = 0; k < length-1; k++){
                System.out.print(" " + "*");
            }
            System.out.println("");
        }

Hope this will solve your problem.
