Java Code To Print Pyramid and Patterns

We will draw half pyramids, inverted pyramids, full pyramids, inverted full pyramids, Pascal’s triangle, and Floyd’s triangle in Java Programming.

Code

public class PyramidPattern {

	public static void main(String[] args) {
		for(int i=1; i<=5; i++) {
			
			for(int j=1; j<= i; j++) {
				System.out.print("* ");
			}
			
			System.out.println("");
		}
	}
	
}

            for (int j = 1; j <= 5 - i; j++) {
                System.out.print(" ");
