???

   public mergerTxt()
   {
      try 
     {
File file = new File( "us-skype.lang" ); // get file name
File fileRu = new File( "ru-skype.lang" ); // get file name
File file2 = new File( "skype6bufferedAll.lang" ); 
		BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream (file), "UTF-8"));
		BufferedReader readerRu = new BufferedReader(new InputStreamReader(new FileInputStream (fileRu), "UTF-8"));
		BufferedWriter output = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file2), "UTF-8")); 
         String result; // result from checking file
         String result2; // result from checking file
         String result3; // result from checking file
         int dot ;
		 int dot2;
         int i=1;		 
         // file does exist
         if ( file.exists() ) 
         { 
        while  ( i<3306 ) 
            {   
			i++;
               result = reader.readLine(); // read a line from file
               result2 = readerRu.readLine(); // read a line from file
            dot = result.lastIndexOf("=");
            dot2 = result2.lastIndexOf("=");
		    result3 = result.substring(dot + 1) + " = " + result2.substring(dot2 + 1);
			output.write( result3 + "\n" ); // output line of file


            } // end while
         } // end if

Check if the returned character is null. If it is null that mean it is eof. Check API documentation for further information.

I used below but the resulting file rather have 3306 lines (as the two merged files eng(1)=ru(2))ha s only 3201 lines, this is memory problem...how to fix?

            while  ( true ) 
            {   
			i++;
               result = reader.readLine(); 			   if (result==null) { break; }
               result2 = readerRu.readLine();
