Pascal’s triangle is a triangular array of the binomial coefficients.
Program to Display Pascal Triangle in java
class Main { public static void pascalTriangle(int n) { for (int j = 0; j < n; j++) { int num = 1; System.out.printf("%" + (n - j) * 2 + "s", ""); for (int k = 0; k <= j; k++) { System.out.printf("%4d", num); num = num * (j - k) / (k + 1); } System.out.println(); } } public static void main(String[] args) { int n=6; pascalTriangle(n); } }
OutPut:-
1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 1 5 10 10 5 1
