Java keep printing a new line in my recursive method

Question

I am trying to write a recursive method to print n number of asteriks in a line and create a new line at the end.

So, TriangleOps.line(5);

would print

    *****

This is the code I wrote:

    public static void line (int n){
    if(n>0){
    System.out.println("*");
    line(n-1);
    }}

instead it prints

with a lot of space at the end. Can anyone tell me how to remove the line breaks?

`println` prints a newline: use `System.out.print`, and then a `println` at the base case to get the newline — pb2q, Oct 14 '12 at 03:33

Use

System.out.print();

instead

println(); method adds new line character at the end by it self

and then put a println after you are done putting out all the *s. – arcy Oct 14 '12 at 03:34

Modify the println to print and add a println at the end:

public static void line(int n) {
    if (n > 0) {
        System.out.print("*");
        line(n - 1);
    }
    System.out.println();
}

Type System.out.print(); to overwrite

println(); by doing this the method adds new line character at the end by itself
