一个解决java.io.EOFException的方法

 

 

纪录一下解决java.io.EOFException的方法

package onlyfun;

import java.io.*;
import java.util.*;

public class Test_5 {

    List list = new ArrayList();
    DataOutputStream dos = null;
    OutputStream out = null;
    DataInputStream dis = null;
    InputStream is = null;

    public static void main(String[] args) {
        new Test_5();
    }

    public Test_5() {
        list.add("first");
        list.add("second");
        list.add("third");

        write();
        List ret = read();
        Iterator it = ret.iterator();
        while(it.hasNext()) {
            String temp = (String)it.next();
            System.out.println(temp);
        }
    }

    public void write() {
        try {
            out = new FileOutputStream("test.txt");
            dos = new DataOutputStream(out);

            for(int i=0; i
                String str = list.get(i);
                dos.writeUTF(str);
            }

            if(out != null) {
                out.close();
                out = null;
            }
        } catch (FileNotFoundException e1) {
            e1.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public List read() {
        List ret = new ArrayList();

        try {
            is = new FileInputStream("test.txt");
            dis = new DataInputStream(is);

            String temp = null;
            temp = dis.readUTF();
            while(temp != null) {
                ret.add(temp);
                if(dis.available()>0) {
                    temp = dis.readUTF();
                }
                else {
                    break;
                }
            }

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return ret;
    }

}

以下为出错时的代码：read（）方法

 

    public List read() {
        List ret = new ArrayList();

        try {
            is = new FileInputStream("test.txt");
            dis = new DataInputStream(is);

            String temp = null;
            temp = dis.readUTF();
            while(temp != null) {
//              ret.add(temp);
//              if(dis.available()>0) {
//                  temp = dis.readUTF();
//              }
//              else {
//                  break;
//              }
                ret.add(temp);
                temp = dis.readUTF();
            }

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return ret;
    }
