We are back with another example of loops in java. In this article, we are going to teach you how to write a Java Program To Print Pyramid. So, let’s start creating the program.
Java Program To Print Pyramid:
In this section, we are discussing the logic of the program to print the pyramid pattern in java. Simply, take the number of rows from the user and used 3 for loops one outer loop, and two inner loops to print this pattern. The first loop iterates from 1 to the number of rows entered by the user and we have to print the spaces. The logic to print the spaces is we entered 7 rows and in the output, we clearly see that there are 6 spaces and 1 star in the first row.
In the second row, the star will increase from 1 to 2 and the number of spaces will decrease from 6 to 5 and it iterates until the spaces beomes zero. It means in every iteration the first loop print the spaces (n-i) and in the second inner loop we will print the star and a space. This time the space is used to print the pyramid neatly and clearly to the user.
Source Code:
import java.util.*;
public class Pyramid {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.print("Enter The Number Of Rows : ");
int n = sc.nextInt();
for(int i =1; i<n ; i++){
for(int j=1 ; j<n-i ; j++){
System.out.print(" ");
}
for(int j =1 ; j<=i ;j ++){
System.out.print("* ");
}
System.out.println();
}
}
}
