ascii pine trees

[justin marshall]

hi,
this is a code to print a pine tree. It just prints one big tier for any number. It works ok for one tier.
But how do I make look like this one?

For example, if you input 3 you get 3 tiers in the tree. Base of tree is always 4 dashes wider then the bottom tier of the tree.

This is what I have so far:

public class PrintTree
{
public static void main (String[] args)
{
int treeHeight, height, spaces, rows, trunk;

// Get the height of the tree
System.out.print("Enter a number: ");
treeHeight = <method to get stuff from keyboard>;

// Loop once for each row of the tree.
for (height=1; height <= treeHeight; height++)
{
// Print the number of spaces in rows of
// the tree.
for (spaces = 1; spaces <= treeHeight-height; spaces++)
{
System.out.print(" ");
}
// Print out the rows of the tree.
for (rows = 1; rows <= (2*height - 1); rows++)
{
System.out.print("*");
}
// Go on to the next line of the tree.
System.out.println();
}
// Print the trunk of the tree. 
for (trunk = 1; trunk <= treeHeight/4; trunk++)
{
// Print out the leading spaces.
for (spaces=1; spaces <= treeHeight - 2; spaces++)
{
System.out.print("-");
}
// Print out the trunk.
System.out.print(" ");
System.out.print("|");
System.out.println();

}
System.out.println();
}
}

This seems to work OK, but there's probably simpler ways

class PineTree
{
  public static void main(String args[])
  {
    int tiers = Integer.parseInt(args[0]) + 1;
    int base = tiers*2 -1 +4;
    String pad = "";
    String branch = "";
    for(int i = 2; i <= tiers; i++)
    {
      for(int ii = 1; ii <= i; ii++)
      {
        pad = "";
        branch = "";     
        for(int x = base/2 -ii +1; x > 0 ; x--) pad += " ";
        for(int y = 0; y < ii*2 -1; y++) branch += "*";
        System.out.println(pad+branch);
      }
    }
    for(int i = 0; i <= base/2 -1; i++) System.out.print(" ");
    System.out.println("|");
    for(int i = 0; i < base; i++)
    {
      System.out.print("-");
      if(i == base/2-1) System.out.print("+");
    }
    System.out.println();
    System.exit(0);
  }
}

This isn't homework, is it?

[justin marshall]

no, no it's not homework.
I learn by example. I learned C that way.
thanks for asking though.
justin.
