InputStreamReader（字符输入转换流 ）
- 解决不同编码时，字符流读取文本内容乱码的问题
public static void main(String[] args) {try (//1.得到文件的原始字节流(GBK的字节流形式)FileInputStream is = new FileInputStream("src/666.txt");//2.把原始的字节流输入按照指定的字符集编码转换成字符输入流InputStreamReader isr = new InputStreamReader(is, "GBK");//3.再转换成缓冲流BufferedReader br = new BufferedReader(isr)) {String line;while((line = br.readLine()) != null){System.out.println(line);}} catch (Exception e) {e.printStackTrace();}}OutputStreamWriter（字符输出转换流 ）
public static void main(String[] args) {try (FileOutputStream os = new FileOutputStream("src/666.txt");OutputStreamWriter osw = new OutputStreamWriter(os,"GBK");BufferedWriter bw = new BufferedWriter(osw)) {bw.write("我是你爹");bw.newLine();bw.write("我是你爹");} catch (Exception e) {e.printStackTrace();}}
