[FIXED] How to print int n values

Issue

I am new to Java and just start my journey but i have problem with this simple function. I am should have result like that *2345 **345 ***45 ****5 But my function return something else :D What should I have to change?

public class Main08 {

    public static void main(String[] args) {
        int n = 5;
        for (int i = 0; i < n; i++) {
            String row = "";
            for (int j = 0; j < n; j++) {
                if (j < n) {
                    System.out.println(row += "*");}
                 else {
                    System.out.print(n);}
            }
        }
    }
}

Solution

You can try like this:

public class MyClass {
    public static void main(String[] args) {
        int n = 5;
        for (int i = 0; i < n - 1; i++) {
            for (int j = 0; j < n; j++) {
                if (j <= i) {
                    System.out.print("*");
                } else {
                    System.out.print(j + 1);
                }
            }
            System.out.print(" ");
        }
    }
}

Your issue is, that you prolonged the string multiple times and every time print it out again. I changed it such, that I only print out the numbers and asterisks depending on how the i and j relate to each other.

Also i limit the outer loop to n-1, because otherwise you will print 6 blocks (because you are starting from zero) and have a block of only asterisks at the end.

Output: *2345 **345 ***45 ****5
