java十七（字符字节流的转换）

* InputStreamReader：字节输出转换为字符输出

* OutStreamWriter：字节输入转换为字符输入

案例

package File类;

import java.io.*;
import java.nio.charset.Charset;

public class 字节字符转换流 {
    public static void main(String[] args) throws IOException {
        InputStream inputStream = new FileInputStream("1.js");
        OutputStream outputStream = new FileOutputStream("1.js");

        out(outputStream);
        in(inputStream);
    }

    public static void in(InputStream in) {
        try {
            Reader reader = new InputStreamReader(in, Charset.defaultCharset());
            char[] chars = new char[1024];
            int len = -1;
            while ((len = reader.read(chars)) != 1) {
                System.out.println(new String(chars, 0, len));
            }
            reader.close();
        } catch (Exception e) {

        }

    }

    public static void out(OutputStream out) throws IOException {
        Writer writer = new OutputStreamWriter(out,Charset.defaultCharset());
        writer.write(",我是新增加");
        writer.close();
    }
