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.

import java.util.Scanner;

public class DashLine {

public static void main(String[] args) {

// Declaring variables

int n;

/*

* Creating an Scanner class object which is used to get the inputs

* entered by the user

*/

Scanner sc = new Scanner(System.in);

// Getting the input entered by the user

System.out.print("Enter a number :");

n = sc.nextInt();

// calling the method by passing the user entered input as argument

dashedLine(n);

}

//This method will print the dashed line for number greater than zer

private static void dashedLine(int n) {

if (n > 0) {

for (int i = 1; i <= n; i++) {

System.out.print("-");

}

System.out.println();

}

}

}

Explanation:

b.. i believe would be the right one sorry if im wrong.
