举例说明使用BufferedReader时出现乱码时的解决方法

解决方法如下：

BufferedReader br=new BufferedReader(new InputStreamReader(connectiton.getInputStream(),"GB2312"));

或者

BufferedReader br=new BufferedReader(new InputStreamReader(connectiton.getInputStream(),"GBK"));

具体举例：

FileInputStream fileInputStream = new FileInputStream("文件路径");

InputStreamReader inputStreamReader = new InputStreamReader(fileInputStream,"GB2312");//或者"GBK"

BufferedReader br= new BufferedReader(inputStreamReader);

现以第二届ITAT大赛最后一道编程题为例

1．编写一个Java程序要求：开启一个文本文件，一次读取其内的一行文本。令每一行形成一个String，并将读出的String对象置于LinkedList中。请以相反次序印出LinkedList内的所有文本行。

package MyTest;

import java.io.*;

import java.util.LinkedList;

import java.util.ListIterator;

/**

public class Test22 {

public static void main(String args[]) throws FileNotFoundException, IOException {

//FileReader fr = new FileReader("D:/我的文档/NetBeansProjects/IT/src/MyTest/c.txt");

FileInputStream fr=new FileInputStream("D:/我的文档/NetBeansProjects/IT/src/MyTest/b.txt");

InputStreamReader is=new InputStreamReader(fr,"GB2312");

BufferedReader br = new BufferedReader(is);

LinkedList ll = new LinkedList();

String s;

while ((s = br.readLine()) != null) {

ll.addFirst(s);

}

br.close();

ListIterator li = ll.listIterator(ll.size());

while (li.hasPrevious()) {

System.out.println(li.previous());

}

}

}
