Java program to display Floyd's triangle, in the triangle, there are n integers in the nth row and a total of (n(n+1))/2 integers in n rows. It is a simple pattern to print but helpful in learning how to create other patterns. The key to develop patterns is using nested loops appropriately.
Floyd's triangle Java program
public static void main(String args)
int n, num = 1, c, d;
Scanner in = new Scanner(System.in);
System.out.println("Enter the number of rows of Floyd's triangle to display");
n = in.nextInt();
for (c = 1; c <= n; c++)
for (d = 1; d <= c; d++)
System.out.println(); // Moving to next row
