Java修炼——键盘输入，字节转换流

键盘控制输入字符，并且有转换流（InputStreamReader）加入，同样也是使用了缓冲。

package com.bjsxt.ioproject;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.UnsupportedEncodingException;

public class TestSystemin {
	public static void main(String[] args) {
		BufferedReader br=null;
		BufferedWriter bw=null;
		try {
			InputStream is=System.in;
			System.out.println("请输入内容：");
			InputStreamReader isr=new InputStreamReader(is,"gbk");
			br = new BufferedReader(isr);
			bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File("F:\\.......\\资料\\yxf.txt"),true),"gbk"));
			String len=null;
			while (!"over".equals((len=br.readLine()))) {
				bw.write(len);
				bw.newLine();
				bw.flush();
			}
		} catch (UnsupportedEncodingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}finally {
			try {
				if (bw!=null) {
					bw.close();
				}
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			try {
				if (br!=null) {
					br.close();
				}
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}

	}
}
