Java-字节流转字符流的转换流

字节流转字符流所使用的转换流为：InputStreamReader

字符流转字节流所使用的转换流为：OutputStreamWriter

InputStreamReader的实例：

import java.io.*;
import java.lang.String;
//字节流转字符流 转换流
public class Test {
    public static void main(String[] args) throws IOException {
        FileInputStream fis = new FileInputStream("d:\\Options.ini"); //字节输入流对象
        InputStreamReader isr = new InputStreamReader(fis); //字节流转字符流的转换流对象
        BufferedReader br = new BufferedReader(isr);    //缓冲流对象
        String inString = null; //用来存放缓冲流内容的字符串
        while ((inString = br.readLine()) != null) { //当inString不为空时，代表有数据可读
            System.out.println(inString);   //输出
        }
    }
}

OutputStreamWriter的实例：

import java.io.*;
import java.lang.String;
import java.util.Scanner;

//字符流转字节流 转换流
public class Test {
    public static void main(String[] args) throws IOException {
        OutputStreamWriter osw = new OutputStreamWriter(System.out); //创建字符流转字节流对象
        Scanner sc = new Scanner(System.in);  //创建Scanner对象
        String outString = sc.next();  //创建字符串对象获取输入
        osw.write(outString);  //将获取到的字符串以字节流的形式输出到控制台
        osw.close();  //关闭管道

        FileOutputStream fos = new FileOutputStream("d:\\index.txt");
        OutputStreamWriter osw2 = new OutputStreamWriter(fos);
        osw2.write("ABCDEFG");
        osw2.close();
    }
}
