How to solve the problem of garbled characters when reading csv files in Java

csv文件默认编码为ANSI,java读取CSV出现乱码主要是编码不一致问题。(推荐:java视频教程

DataInputStream in = new DataInputStream(new FileInputStream(new File("d:\\*.csv"))); BufferedReader br= new BufferedReader(new InputStreamReader(in,"GBK"));//这里如果csv文件编码格式是utf-8,改成utf-8即可

InputStreamReader类是从字节流到字符流的桥接器:它使用指定的字符集读取字节并将它们解码为字符。 它使用的字符集可以通过名称指定,也可以明确指定,或者可以接受平台的默认字符集。

BufferedReader类从字符输入流中读取文本并缓冲字符,以便有效地读取字符,数组和行。Reader构成的对象是字符对象,每次的读取请求都会涉及到字节读取解码字符的过程,而BufferedReader类中有设计减少这样的解码次数的方法,进而提高转换效率。
