java program to print pascal triangle code example
Example 1: Java program to display pascal triangle
import java.util.Scanner;
public class PascalsTriangleJava
{
static int findFactorial(int number)
{
int factorial;
for(factorial = 1; number > 1; number--)
{
factorial *= number;
}
return factorial;
}
// here's the function to display pascal's triangle
static int printPascalTraingle(int num, int p)
{
return findFactorial(num) / (findFactorial(num - p) * findFactorial(p));
}
public static void main(String[] args)
{
int row, a, b;
System.out.println("Please enter number of rows: ");
Scanner sc = new Scanner(System.in);
row = sc.nextInt();
System.out.println("Here's is pascal's triangle: ");
for(a = 0; a < row; a++)
{
for(b = 0; b < row - a; b++)
{
System.out.print(" ");
}
for(b = 0; b <= a; b++)
{
System.out.print(" " + printPascalTraingle(a, b));
}
System.out.println();
}
sc.close();
}
}
