Not sure I understand what you wish to do. Correct me if I am wrong, but you
want to read a file that another program wrote.
Simple to do..
Example:
package filereader;
import java.io.*;
public class ReadFile {
public ReadFile() {
}
private String ReadTheFile(String fileName) throws IOException{
File file= new File(fileName);
char fData[]= new char[(int)file.length()];
String sResult="";
try {
if (file.exists()) {
BufferedReader br = new BufferedReader(new FileReader(file));
while (br.read() != -1) {
br.read(fData);
}
sResult=new String(fData);
}
else
sResult="File "+fileName+ " was not found.";
}
catch(IOException ioex) {
System.out.println("tError reading file "+fileName);
}
return sResult;
}
public static void main (String args[]) {
ReadFile rf= new ReadFile();
String sData="";
try {
sData=rf.ReadTheFile("/home/paul2/somwfile.log");
}
catch (Exception ex) {
ex.printStackTrace();
}
System.out.println("t The Data contained in the file is: n");
System.out.println(sData);
System.out.println("ntEnd of File Data");
}
}
