Java中如何处理读取文件时中文乱码问题呢?

InputStreamReader 
    设置编码,即可避免中文乱码现象

InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("xxx");
 
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream);
while(reader.ready()){
 
    String line = reader.readLine();
    System.out.println(line);
}
reader.close();
inputStream.close();


有时
   文件是utf-8
   Java默认是能读的
  有的是GBK
  可使用InputStreamReader设置编码

InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("xxx");
 
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "gbk");
while(reader.ready()){
 
    String line = reader.readLine();
    System.out.println(line);
}
reader.close();
inputStream.close();
