资源泄漏:“in"永远不会关闭 [英] Resource leak: 'in' is never closed

问题描述

为什么 Eclipse 在下面的代码中给我温暖的资源泄漏:'in'从未关闭"?

Why does Eclipse give me the warming "Resource leak: 'in' is never closed" in the following code?

public void readShapeData() {
        Scanner in = new Scanner(System.in);
        System.out.println("Enter the width of the Rectangle: ");
        width = in.nextDouble();
        System.out.println("Enter the height of the Rectangle: ");
        height = in.nextDouble();

推荐答案

因为你没有关闭你的 Scanner

Because you don't close your Scanner

in.close();
