以字节流读入文件(内容包括中文)时显示乱码
public static void main(String[] args) throws 
IOException{		
		byte[] bytes = new byte[3]; //		
		File file = new File("c:/a.txt");		
		FileInputStream fis = new FileInputStream(file);		
		StringBuffer request1 = new StringBuffer();		
		while(fis.read(bytes)!= -1)
		{
		   request1.append(new String(bytes));  		    
		}				
		System.out.println(request1.toString());		
}
问题:1. java是如何处理中文字的(编码方式是什么)
       2. 若数组长度是2的倍数则能正常显示,是不是中文字是占两个字节的
       3. 有没有更好的读取方法
------解决方案--------------------
Java code
FileReader fr = new FileReader("c:/a.txt");
BufferedReader br = new BufferedReader (fr)
String line = "";
StringBuffer request1 = new StringBuffer();
while((line = br.readline()) != null){
    request1.append(line);  
}
System.out.println(request1.toString());
