Question

for these guidelines:

Write the definition of a method dashedLine , with one parameter, an int .

If the parameter is negative or zero, the method does nothing. Otherwise it prints a complete line terminated by a newline to standard output consisting of dashes (hyphens) with the parameter’s value determining the number of dashes. The method returns nothing.

I wrote the following code, but it only prints one hyphen when I run in eclipse and give it a test parameter of 5. I’m thinking I may need to use a for loop instead. I think it loops within the loop therefor only giving one hyphen back.

how can I ‘remedy’ this code?

void dashedLine(int x)
    {
        int i=0;
        if(x>0) 
            {
            if(i<=x)
                {
                    i++;
                    System.out.print("-");
                }
                else
                    System.out.print("\n");

            }
    }

Answer 1

But there is no loop. if is not a loop. for while and do while are the three different loops in Java. You should rather have:

void dashedLine(int x)
{
    for (int i=0;i<x;i++) {
        System.out.print("-");
    }
    System.out.print("\n");
}
