How can I ignore a blank line in a srt file using Java

Question

I have a srt file like below and I want to remove blank line : in line no 3

**
1
Line1: 00:00:55,888 --> 00:00:57,875.  
Line2:Antarctica  
Line3:   
Line4:2  
Line5:00:00:58,375 --> 00:01:01,512  
Line6:An inhospitable wasteland.    
**

        FileInputStream fin = new FileInputStream("line.srt");
        FileOutputStream fout = new FileOutputStream("m/line.srt");
        int i = 0;
        while(((i =fin.read()) != -1)){
            if(i != 0)
            fout.write((byte)i);
        }

There you go. Steps:

1) FileInputStream fin = new FileInputStream("line.srt"); this is to get the file to a bufferedreader in the next step

2) BufferedReader reader = new BufferedReader(new InputStreamReader(fin)); get the text file to a buffereader

3) PrintWriter out = new PrintWriter("newline.srt"); use a print writer to write the string of every line in the new text file

4) String line = reader.readLine(); read next line

5) while(line != null){ if (!line.trim().equals("")) { check that line is not null and that line is not empty

6) out.println(line); write line (not empty) to the output .srt file

7) line = reader.readLine(); get new line

8) out.close(); close PrintWriter in the end...

import java.io.*;
class RemoveBlankLine {
    public static void main(String[] args) throws FileNotFoundException, IOException{
        FileInputStream fin = new FileInputStream("line.srt");
        BufferedReader reader = new BufferedReader(new InputStreamReader(fin));
        PrintWriter out = new PrintWriter("newline.srt");
        int i = 0;
        String line = reader.readLine();
        while(line != null){
                    if (!line.trim().equals("")) {
                        out.println(line);
                    }
                    line = reader.readLine();
                }    
            out.close();
    }
}

INPUT:

**
1
00:00:55,888 --> 00:00:57,875.  
Antarctica  

2  
00:00:58,375 --> 00:01:01,512  
An inhospitable wasteland.    
**

OUTPUT:

**
1
00:00:55,888 --> 00:00:57,875.  
Antarctica  
2  
00:00:58,375 --> 00:01:01,512  
An inhospitable wasteland.

By the way, make sure you are clear when you ask your questions, because the way you state your problem I assumed Line1, Line2, etc are part of your input file, and I have prepared another solution which I had to change... Make sure you are clear and precise so that you get the proper answers !
