# Java Program to Create Pyramid and Pattern

In this article, we will understand how to create pyramid and pattern. The pattern is formed by using multiple for-loops and print statements.

Below is a demonstration of the same −

Input

Suppose our input is −

The number of rows is defined as 8

Output

The desired output would be −

The pyramid pattern :
1
2 3 2
3 4 5 4 3
4 5 6 7 6 5 4
5 6 7 8 9 8 7 6 5
6 7 8 9 10 11 10 9 8 7 6
7 8 9 10 11 12 13 12 11 10 9 8 7
8 9 10 11 12 13 14 15 14 13 12 11 10 9 8

## Algorithm

Step 1 - START
Step 2 - Declare six integer values namely my_input, k, i, my_count, my_temp and my_spaces.
Step 3 - Read the required values from the user/ define the values
Step 4 - Assign value of 0 to ‘k’, my_count and my_temp
Step 5 - We iterate through two nested 'for' loops to get space between the characters.
Step 6 - After iterating through the innermost loop, we iterate through another 'for' loop. This will help print the value of (i + k - 2 * my_temp).
Step 7 - Now, print a newline to get the specific number of characters in the subsequent lines.
Step 8 - Display the result
Step 9 - Stop

## Example 1

Here, the input is being entered by the user based on a prompt. You can try this example live in our coding ground tool .

import java.util.Scanner;
public class Pyramid {
public static void main(String[] args) {
int my_input, k, i, my_count, my_temp, my_spaces;
my_input = 8;
k = 0;
my_count = 0;
my_temp = 0;
System.out.println("Required packages have been imported");
Scanner my_scanner = new Scanner(System.in);
System.out.println("A reader object has been defined ");
System.out.print("Enter the number of rows: ");
my_input = my_scanner.nextInt();
System.out.println("The pyramid pattern : ");
for ( i = 1; i <= my_input; ++i) {
for (my_spaces = 1; my_spaces <= my_input - i; ++my_spaces) {
System.out.print(" ");
++my_count;
}
while (k != 2 * i - 1) {
if (my_count <= my_input - 1) {
System.out.print((i + k) + " ");
++my_count;
} else {
++my_temp;
System.out.print((i + k - 2 * my_temp) + " ");
}
++k;
}
my_temp = my_count = k = 0;
System.out.println();
}
}
}

## Output

Required packages have been imported
A reader object has been defined
Enter the number of rows: 8
The pyramid pattern :
1
2 3 2
3 4 5 4 3
4 5 6 7 6 5 4
5 6 7 8 9 8 7 6 5
6 7 8 9 10 11 10 9 8 7 6
7 8 9 10 11 12 13 12 11 10 9 8 7
8 9 10 11 12 13 14 15 14 13 12 11 10 9 8

## Example 2

Here, the integer has been previously defined, and its value is accessed and displayed on the console.

public class Pyramid {
public static void main(String[] args) {
int my_input, k, i, my_count, my_temp, my_spaces;
my_input = 8;
k = 0;
my_count = 0;
my_temp = 0;
System.out.println("The number of rows is defined as " +my_input);
System.out.println("The pyramid pattern : ");
for ( i = 1; i <= my_input; ++i) {
for (my_spaces = 1; my_spaces <= my_input - i; ++my_spaces) {
System.out.print(" ");
++my_count;
}
while (k != 2 * i - 1) {
if (my_count <= my_input - 1) {
System.out.print((i + k) + " ");
++my_count;
} else {
++my_temp;
System.out.print((i + k - 2 * my_temp) + " ");
}
++k;
}
my_temp = my_count = k = 0;
System.out.println();
}
}
}

## Output

The number of rows is defined as 8
The pyramid pattern :
1
2 3 2
3 4 5 4 3
4 5 6 7 6 5 4
5 6 7 8 9 8 7 6 5
6 7 8 9 10 11 10 9 8 7 6
7 8 9 10 11 12 13 12 11 10 9 8 7
8 9 10 11 12 13 14 15 14 13 12 11 10 9 8
