Star Patterns

Print a simple right-angled triangle star pattern.

JavaBeginner

Java

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

Output

*
**
***
****
*****

Again we use nested loops, printing one more star per row.
