BufferedReader乱码问题解决

当我们用BufferedReader读取文件，文件中含有中文时会出现乱码问题。这是编码方式不对应造成的。解决方式如下：

创建InputStreamReader实例时指定以何种方式读取文件

public static void main(String[] args) {
        File file = new File("f:/trigger.txt");
        try {
            FileInputStream fs = new FileInputStream(file);
        //    FileReader reader = new FileReader(file);
            BufferedReader br = new BufferedReader(new InputStreamReader(fs, "gbk"));
            while (br.ready()) {
                String str = br.readLine();
                System.out.println(str);
            }
            br.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
