JAVA 打开文件乱码 解决办法
String Data_Path = "D:/file_jiucool.txt";
File file = new File(Data_Path);
String line= "";
if(file.exists()){
FileReader reader = new FileReader(Data_Path);
BufferedReader bufferedreader= new BufferedReader(reader);
while((line = bufferedreader.readLine())!=null){
line = new String(line.getBytes(), "UTF-8");
System.out.println(line);
}
}上述代码中，设置为GBK、GB2312 时全部为乱码，设置为UTF-8时，最后一个汉字为乱码，是不是很让人郁闷？正确代码如下：
String Data_Path = "D:/file_jiucool.txt";
File file = new File(Data_Path);
String line= "";
if(file.exists()){
//FileReader reader = new FileReader(Data_Path);
//BufferedReader bufferedreader= new BufferedReader(reader);
InputStreamReader isr = new InputStreamReader(new FileInputStream(file), "UTF-8");
BufferedReader bufferedreader = new BufferedReader(isr);
while((line = bufferedreader.readLine())!=null){
//line = new String(line.getBytes(), "UTF-8");
System.out.println(line);
}
}
所以，在读取文件的时候就得进行编码设置，而不是读完文件输出时再设置编码！
