Thread: Resource leak: 'in' is never closed..?

Hello everyone! I need help with two things:
1. I get this warning "Resource leak: 'in' is never closed". Why?
2. After every convert is done I want the following message to be printed(example): "1500 miles equals to 2414.02 kilometers". How do I do that?
Thank you

import java.util.Scanner;
 
public class Convert {
 
	public static void main(String[] args) {
 
	Scanner in = new Scanner (System.in);
 
	float miles;
	float feet;
	float galons;
	float km1, km2;
	float meters1, meters2;
	float liters1, liters2;
 
	System.out.println("Miles:");
	miles = in.nextFloat();
	km1 = (float) (miles * 1.609344);
	km2 = (float) (Math.round(km1*100.0)/100.0);	
	System.out.println("Kilometers ="+km2);
 
	System.out.println("Feet:");
	feet = in.nextFloat();
	meters1 = (float) (feet * 0.3048);
	meters2 = (float) (Math.round(meters1*100.0)/100.0);	
	System.out.println("Meters = "+meters2);
 
	System.out.println("Galons:");
	galons = in.nextFloat();
	liters1 = (float) (galons * 3.78541178);
	liters2 = (float) (Math.round(liters1*100.0)/100.0);	
	System.out.println("Liters "+liters2);
	}
}

You're using a Scanner object but not closing. At the bottom of your program, close the Scanner via in.close();

2. After every convert is done I want the following message to be printed(example): "1500 miles equals to 2414.02 kilometers". How do I do that?

You can use variables with your System.out.println statements -- shoot, you're already doing that. So what have you tried and what isn't working with your attempt to do this?

You're welcome!
