java读取txt文本中如含有中文,可能会出现乱码,解决方案是: 
1.要统一编码,java工程的编码,txt文本编码,java工程中的java文本编码都统一为utf-8; 
2.利用 InputStreamReader(new FileInputStream(fileUrl), "utf-8")将文本再次设置为utf-8 
3.具体代码如下 

复制代码代码如下:

InputStreamReader isr;  
  
try {  
  
isr = new InputStreamReader(new FileInputStream(fileUrl), "utf-8");  
  
BufferedReader read = new BufferedReader(isr);  
  
String s=null;  
  
List<String> list = new ArrayList<String>();  
  
while((s=read.readLine())!=null)  
  
{  
  
//System.out.println(s);  
  
if(s.trim().length()>1){  
  
list.add(s.trim());  
  
}  
  
}  
  

System.out.println("OK!");  
  
} catch (UnsupportedEncodingException e) {  
  
// TODO Auto-generated catch block  
  
e.printStackTrace();  
  
} catch (FileNotFoundException e) {  
  
// TODO Auto-generated catch block  
  
e.printStackTrace();  
  
} catch (IOException e) {  
  
// TODO Auto-generated catch block  
  
e.printStackTrace();
