This is the time to ask for your code.
Yes sir,
This is the code for read a file from "/root/test.txt" and write out into a file called "/root/abc.txt". It tested runable without bug
QUOTE
package test;
import java.io.*;
public class Test1 {
public static void main(String [] args)
{
File file1 = new File("/root/test.txt");
try{
BufferedReader in = new BufferedReader(new FileReader(file1));
BufferedWriter out = new BufferedWriter(new FileWriter("/root/abc.txt"));
String line = in.readLine();
while(line !=null)
{
System.out.println(line);
out.write(line+"\n");
line = in.readLine();
}
in.close();
out.close();
}
catch(Exception e)
{
}
}
}
The code support put into which part? I choose the ProgressMonitorDemo code sample...
Here is the source from java.sun
