Answer 1

public class NestedLoops {

    public static void main(String[] args) {
        // change these variables if you want some other pattern
        int numStars = 6;
        int numForwardSlashes = 12;
        int numBackwardSlashes = 0;
        int numLines = 3;

        for (int i = 0; i < numLines; i++) {
            for (int j = 0; j < numStars; j++) {
                System.out.print("*");
            }
            System.out.print(" ");
            for (int j = 0; j < numForwardSlashes; j++) {
                System.out.print("/");
            }
            for (int j = 0; j < numBackwardSlashes; j++) {
                System.out.print("\\");
            }
            System.out.print(" ");
            for (int j = 0; j < numStars; j++) {
                System.out.print("*");
            }
            System.out.println();
            numStars--;
            numForwardSlashes -= 2;
            numBackwardSlashes += 2;
        }
    }
