A resource is an object that must be closed after the program is finished with it. The try-with-resources statement ensures that each resource is closed at the end of the statement. Any object that implements java.lang.AutoCloseable, which includes all objects which implement java.io.Closeable, can be used as a resource. 谷歌翻译： try-with-resources语句是声明一个或多个资源的try语句。 资源是一个对象，程序完成后必须将其关闭。 try-with-resources语句可确保在语句末尾关闭每个资源。 任何实现java.lang.AutoCloseable的对象（包括所有实现java.io.Closeable的对象）都可以用作资源。 Java中的 try(){} 标签：包括 class manage ini targe must 关闭 detail input 原文地址：https://www.cnblogs.com/gyjjj/p/14526507.html
从网上查阅资料得知从 Java 7 build 105 版本开始，Java 7 的编译器和运行环境支持新的 try-with-resources 语句，称为 ARM 块(Automatic Resource Management) ，自动资源管理：
//src
public abstract class InputStream implements Closeable {
// MAX_SKIP_BUFFER_SIZE is used to determine the maximum buffer size to
// use when skipping.
private static final int MAX_SKIP_BUFFER_SIZE = 2048;
//...
}
