Comments Off on Java Inverted Right Triangle Star Pattern Program | Patterns. Run one inner loop. Two for loops are used to print the triangle. The first loop within the outer loop is used to print the spaces before each star. For a right triangle number pattern of N rows, outer for loop will iterate N time (from i = 1 to N). public class RightTriangle { It will print similar output. I never thought about the fact that doubles weren't really accurate (sorry, just trying to say what I did in simple terms). StdDraw.line(0.5, 0.5, 0.9, 0.5); }. It will give output as like below: We can also replace the for loops with while loops.
