JAVA字符流中的编码解码问题2。144

InputStreamReader 是字节流到字符流的桥梁

OutputStreamWriter 是字符流到字节流的桥梁

    import java.io.*;
    
    public class ConversionstreamDemo {
        public static void main(String[] args) throws IOException {
            OutputStreamWriter osw = new OutputStreamWriter(new FileOutputStream("./1.txt"),"GBK");
            osw.write("中国");
            osw.close();
    
            //字符输入流可以查看指定编码内容
    
            InputStreamReader isr = new InputStreamReader(new FileInputStream("./1.txt"),"GBK");
            int ch;
            while ((ch=isr.read())!=-1){
                System.out.print((char)ch);
            }
    
        }
    }
