Program to Print Christmas Tree Star Pattern
Java christmas tree: In this article we are going to see how to print the Christmas tree pattern.
Example-1 When height Of Tree value=10 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * | | | | | | | | | | | | | | | | | |
Example-2: When height Of Tree value=5 * * * * * * * * * * * * * * * | | | | | | | |
Now, let’s see the actual program to print it.
Practice Java programming from home without using any fancy software just by tapping on this Simple Java Programs for Beginners tutorial.
Approach:
- Enter the height of the Christmas tree in an integer variable
heightOfTree. - Take first for loop to print the full height of the tree.
- Take second/inner for loop to print the column values (i.e. stars and spaces).
- Then use another for loop for the lower part of the tree.
JAVA Code:
Method-1 : Static Star Character
import java.util.Scanner;
class Main
{
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
System.out.print("Height Of The Christmas Tree : ");
//Taking height Of Tree as input from user
int heightOfTree=scan.nextInt();
//Outer loop for the upper part of the tree
for(int r = 1;r<=heightOfTree;r++)
{
for(int c = heightOfTree-r; c > 0; c--)
//Inner loop to print the spaces
System.out.print(" ");
for(int d = 1;d<=r;d++)
//Inner loop to print the stars
System.out.print("* ");
//Prints a new line
System.out.println("");
}
//Second outer loop to print the lower part of the tree
for(int r = 1; r<=heightOfTree-1;r++)
{
System.out.print(" ");
for(int c = heightOfTree -3;c>0;c--)
//Inner loop that prints spaces
System.out.print(" ");
for(int d = 2;d>0;d--)
//Inner loop that prints the straight lines
System.out.print("| ");
//Prints a new line
System.out.println();
}
}
}
Method-2 : User Input Character
import java.util.Scanner;
class Main
{
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
System.out.print("Height Of The Christmas Tree : ");
//Taking height Of Tree as input from user
int heightOfTree=scan.nextInt();
System.out.print("Enter any character : ");
//Taking height Of Tree as input from user
char ch=scan.next().charAt(0);
//Outer loop for the upper part of the tree
for(int r = 1;r<=heightOfTree;r++)
{
for(int c = heightOfTree-r; c > 0; c--)
//Inner loop to print the spaces
System.out.print(" ");
for(int d = 1;d<=r;d++)
//Inner loop to print the stars
System.out.print(ch+" ");
//Prints a new line
System.out.println("");
}
//Second outer loop to print the lower part of the tree
for(int r = 1; r<=heightOfTree-1;r++)
{
System.out.print(" ");
for(int c = heightOfTree -3;c>0;c--)
//Inner loop that prints spaces
System.out.print(" ");
for(int d = 2;d>0;d--)
//Inner loop that prints the straight lines
System.out.print("| ");
//Prints a new line
System.out.println();
}
}
}
Output-
Height Of The Christmas Tree : 10
