java - 资源泄漏 conIn 从未关闭

Question

这段代码给我带来了资源泄漏:

conIn never closed

为什么会发生这种情况以及如何解决它？

package homeWork;
import java.util.*;

public class MainClass 
{

    public static void main(String[] args) 
    {
        Scanner conIn = new Scanner (System.in);
        ShoppingBag sb = new ShoppingBag(0.06f);

        int count = 0;
        float cost = 0.0f;

        System.out.print("Enter count (use 0 to stop): ");

        count = conIn.nextInt();
        while (count < 0);
       {
           System.out.print("Enter Cost");
           cost = conIn.nextFloat();
           sb.place(count, cost);

           System.out.print("Enter count (use 0 to stop): ");
           count = conIn.nextInt();
           System.out.print(sb);

       }
    }
}

您没有在 Scanner 对象上调用 conIn.close();。 (docs)
