Program Plan Intro

Print Christmas tree

Program plan:

  • Import the required package.
  • Create a class “ChristmasTree”,
    • Define the method “main()”,
      • Declare the necessary variables.
      • Create “Scanner” object.
      • Prompt the user to enter the number of segments and height of the Christmas tree.
      • Get the number of segments and height from the user.
      • Print new line.
      • Assign the number of segments and height to the variable “m” and “n” respectively.
      • Set the starting row value to “1”.
      • Create “for” loop to iterate till number of segments using “i”,
        • Create “for” loop to iterate till the height of the tree using “j”,
          • Execute “while” loop,
            • Print space.
            • Increment counter variable.
          • Create loop whenever the number of rows greater than the “i” value,
            • Print space.
          • Create loop whenever the “j” value is less than or equal to “i” value,
            • Print “*”.
          • Create loop using the variable “k” whenever the value is less than “i”,
            • Print “*”.
          • Print new line.
        • Increment the starting row.
        • Increment the number of rows.
      • Print stem of the tree as follows,
      • Create loop till the value get from dividing the (number of rows*number of segments-1) by “2”,
        • Print space.
      • Print “*”.
      • Create loop till the value get from dividing the (number of rows*number of segments-1) by “2”,
        • Print space.
      • Print “*”.
      • Create loop till the value get from subtracting “3” from the value which is obtained from dividing the (number of rows*number of segments-1) by “2”,
        • Print the space.
      • Create loop till the value “7”.
        • Print “*”.
