Hi Friend,

Try the following code:

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

class FileConcat {

public static void main (String args []) throws IOException {
Scanner stdin = new Scanner (System.in);
System.out.print ("Enter two text file name with path: ");
String filename1 = stdin.next();
String filename2 = stdin.next();

File file=new File (filename1);
FileInputStream fstream = new FileInputStream(file);
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
while ((strLine = br.readLine()) != null) {
FileWriter fostream = new FileWriter("Master.txt",true);
BufferedWriter output = new BufferedWriter(fostream);
output.write(strLine);
output.newLine();
output.close();
}

File file1=new File (filename2);
FileInputStream fstream1 = new FileInputStream(file1);
DataInputStream in1 = new DataInputStream(fstream1);
BufferedReader br1 = new BufferedReader(new InputStreamReader(in1));
String strLine1;

while ((strLine1 = br1.readLine()) != null) {
FileWriter fostream1 = new FileWriter("Master.txt",true);
BufferedWriter output1 = new BufferedWriter(fostream1);
output1.write(strLine1);
output1.newLine();
output1.close();
}
}
}

Thanks
