  The following code prints the pattern. I have added comments for each block to help you understand its functionality.

  class Diamond
  {
      public static void main(String[] args)
      {
  
          int row = 3;  // row with the maximum stars
          
          // printing rows 1-3
          for (int i=1; i<=row; i++) 
          { 
          	// printing spaces for rows 1-3
              for (int j=row; j>i; j--)
              {
                  System.out.print(" ");
              }
              
          	// printing stars for rows 1-3
              for (int j=1; j<=((i*2)-1); j++) 
              { 
                 System.out.print("*"); 
              } 
              System.out.println(); 
          } 
          
          // printing rows 4,5
          for (int i=row-1; i>=1; i--)
          {
          	// printing spaces for rows 4,5
              for (int j=row-1; j>=i; j--)
              {
                  System.out.print(" ");
              }
              
          	// printing stars for rows 4,5
              for (int j=1; j<=((i*2)-1); j++)
              {
                  System.out.print("*");
              }
              
              System.out.println();
          }
      }
  }

  Here's a simple Python code snippet to print the specified pattern:
  for i in range(1, 4):
  print(" " * (3 - i) + "*" * (2 * i - 1))
  for i in range(2, 0, -1):

  print(" " * (3 - i) + "*" * (2 * i - 1))
