Thread: Basic scanner question

Hi all, this is my first post here.

I'm trying to parse an int and a String into a method using the Scanner and I'm not sure if this is possible? This is what the simple code looks like:

 import java.util.Scanner;
class Actions {
 
	public void move(String direction, int movement) {
 
		System.out.println("Moving " + movement + " metres");
	}
 
 
}
 
public class Robot {
 
public static void main(String[] args) { 
 
	Actions robot1 = new Actions();
	Scanner scan = new Scanner(System.in);
 
	robot1.move(scan.nextLine());
	System.out.println("Enter direction and distance to move");
 
    }
 
}

As you can see I can get user input using scan.nextLine() or nextInt - but is it possible to parse both at the same time? Hope this makes sense.

Thanks for any replies.

I lazily read your question, so I admit I don't completely understand it, but I wanted to add that you CAN use the SAME Scanner object with both methods, nextInt() and nextLine(). However, you lost me with "parse both at the same time." I'm not sure what that means. Either try it or give an example of what that means.

Thanks for the replies - I appreciate that my first post wasn't that clear. I'm trying to get the user to enter a distance (int) and a direction (String) for the "robot" to move in. So user input would look like this:

Attachment 3186

So the distance(int) would be 10 and the robot would move west. I'm trying to ascertain if its possible to scan both an int and a string in the same line of user input - rather than like this:

 System.out.println("Enter distance:");
	robot1.move(scan.nextInt());
 
	System.out.println("Enter direction the robot should move:")
	robot1.direction(scan.nextLine());

^^^ As using the above approach I would need to use two methods rather than one.

Hope that makes sense!

Got it.. thanks!

Try this to parse int into string :

try{
num2 = Integer.parseInt(num1);
}
catch(Exception ex) {
System.out.println("Something went wrong, the string could not be converted to int.");
}
the try-catch is pretty important because the string could contain characters that cannot convert to int, of you need to catch it better than this, but keep it in mind
