从文本中取得的中文显示为??
我的hello.txt已经以utf-8格式保存，在reader中我也指定了编码方式，为什么读出来的还是乱码
...
InputStreamReader isr = new InputStreamReader(new FileInputStream(new File( "hello.txt ")));

InputStreamReader isr = new InputStreamReader(is, "UTF-8 ");

BufferedReader br = new BufferedReader(isr);
String s;
while((s = br.readLine()) !=null){
System.out.print(s);
}
...

[解决办法]
你txt里面的不是utf-8格式的吧
转一下编码吧
[解决办法]
过滤器问题吧

应该是这样:
InputStreamReader isr = new InputStreamReader(new FileInputStream(new File( "hello.txt ")), "UTF-8 ");


BufferedReader br = new BufferedReader(isr);
String s;
while((s = br.readLine()) !=null){
System.out.print(s);
}
