包路径：java.io.InputStreamReader
类名称：InputStreamReader
方法名：<init>

InputStreamReader.<init>介绍

[英]Constructs a new InputStreamReader on the InputStream in. This constructor sets the character converter to the encoding specified in the "file.encoding" property and falls back to ISO 8859_1 (ISO-Latin-1) if the property doesn't exist.
[中]在中的InputStream上构造新的InputStreamReader。此构造函数将字符转换器设置为“file.encoding”属性中指定的编码，如果该属性不存在，则返回ISO 8859_1（ISO-Latin-1）。
