Question

In Chapter 1 you created a program named Triangle in which you displayed a seven-line triangle pattern like the one in Figure 6-33 by using a series of println() statements. Now, using your knowledge of loops, revise the program so that it contains no more than three output statements.

class TriangleWithLoops {
public static void main(String[] args) {
// Write your code here
}
}

Answer 1

class TriangleWithLoops {
    public static void main(String[] args) {
        for (int i = 0; i < 7; i++) {
            for (int j = 0; j <= i; j++) System.out.print("*");
            System.out.println();
        }
    }
}
