The given code prints a right-angled triangle made of asterisks (*
) to the console. The number of rows in the triangle is determined by the variable n
(in this case, 5).
Here's how it works step-by-step:
-
Outer Loop (
for (int i = 1; i <= n; i++)
):- The outer loop controls the number of rows. It iterates from
1
ton
(inclusive). In this case, it iterates 5 times.
- The outer loop controls the number of rows. It iterates from
-
Inner Loop (
for (int j = 1; j <= i; j++)
):- For each iteration of the outer loop, the inner loop runs. The inner loop is responsible for printing the stars (
*
). The number of stars printed in each row corresponds to the current outer loop iteration (i
).
- For each iteration of the outer loop, the inner loop runs. The inner loop is responsible for printing the stars (
-
Printing:
System.out.print("*")
: Prints a star without moving to the next line.System.out.println()
: After the inner loop finishes, this statement moves to the next line.
Output:
The output of the code is a triangle of stars, like this:

Explanation:
- In the first iteration of the outer loop (
i = 1
), one star is printed because the inner loop runs once. - In the second iteration (
i = 2
), two stars are printed. - In the third iteration (
i = 3
), three stars are printed. - This continues until the outer loop finishes after
n
(5) iterations, forming the triangle pattern.
