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();

			}

		}

	}

}
