对文本的操作.

[en152564]

打开1.txt.找到符合条件的行,然后向下再读取2~3行,去掉回车,存至另一文本;
对了....还要去掉重复;多谢多谢先!

文本格式如下:

...

区域:****
姓名:*****
电话:******
备注:***

区域:****
姓名:*****
电话:******

区域:****
姓名:*****
电话:******
备注:***

按楼主的需求，保存的文件跟源文件的区别就是1。没有回车，2。没有重复的,3,没有空行

这样的话很简单
import java.io.*;
public class T1023 {
private File source;
private String dir = ".\\output\\";
public T1023(String file){
source = new File(dir+file);
}

public void store(String filename)throws IOException{
BufferedReader br = new BufferedReader(new FileReader(source));
OutputStream os = new FileOutputStream(dir+filename);
String line = "";
while((line=br.readLine())!=null){
line = line.trim();
if(line.equals("\n"))
continue;
line = line.replaceAll(";{2,}",";");
os.write(line.getBytes());
}
os.close();
br.close();
}

public static void main(String args[])throws IOException{
new T1023("t1023_source.txt").store("t1023.txt");
}
}

//line = line.replaceAll();

}
os.close();
br.close();
}

public static void main(String args[])throws IOException{
System.out.println("\n".trim());
new T1023("t1023_source.txt").store("t1023.txt");
}
