资源泄漏：'in'从不关闭 [英] Resource leak: 'in' is never closed

问题描述

 为什么Eclipse会让我变暖资源泄漏：在以下代码中永远不会关闭？ public void readShapeData（）{
扫描仪in = new Scanner（System.in）; 
 System.out.println（输入Rectangle的宽度）; 
 width = in.nextDouble（）; 
 System.out.println（输入Rectangle的高度）; 
 height = in.nextDouble（）; 
  

解决方案

因为您没有关闭扫描仪

  in.close（）; 
  

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();

解决方案

Because you don't close your Scanner

in.close();
