您是否需要显式关闭Java KeyStore输入流? [英] Do you need to explicity close a Java KeyStore input stream?

问题描述

当使用FileInputStream如下读取KeyStore时，是否需要显式关闭输入蒸汽以防止浪费系统资源?

When reading in a KeyStore using a FileInputStream as follows, does one need to explicitly close the input-steam to stop system resources being wasted ?

FileInputStream fin = new FileInputStream("keystore.jks");
KeyStore keystore = KeyStore.getInstance("JKS");
keystore.load(fin, password);

//  Is this line needed ??
fin.close();

这个FileInputStream是由load()方法自动关闭的，还是需要显式的手动干预?

Is this FileInputStream closed automatically by the load() method or is explicit manually intervention required?
