Read two text files at the same time – Java

I have text files in two different languages, which are aligned line by line That is, the first line in textfile1 should be equal to the first line in textfile2, and so on

Is there any way to read these two files line by line at the same time?

The following is an example of how files should be displayed, assuming that the number of lines per file is approximately 1000000

textfile1：

This is a the first line in English
This is a the 2nd line in English
This is a the third line in English

textfile2：

C'est la première ligne en Français
C'est la deuxième ligne en Français
C'est la troisième ligne en Français

Expected output

This is a the first line in English\tC'est la première ligne en Français
This is a the 2nd line in English\tC'est la deuxième ligne en Français
This is a the third line in English\tC'est la troisième ligne en Français

At present, I can use it, but saving millions in RAM will kill my machine

String english = "/home/path-to-file/english";
String french = "/home/path-to-file/french";
BufferedReader enBr = new BufferedReader(new FileReader(english));
BufferedReader frBr = new BufferedReader(new FileReader(french));

ArrayList<String> enFile = new ArrayList<String>();
while ((line = enBr.readLine()) != null) {
    enFile.add(line);
}

int index = 0;
while ((line = frBr.readLine()) != null) {
    String enSentence = enFile.get(index);
    System.out.println(line + "\t" + enSentence);
    index++;
}

Solution

Place the call nextline on two readers in the same loop:

String english = "/home/path-to-file/english";
String french = "/home/path-to-file/french";
BufferedReader enBr = new BufferedReader(new FileReader(english));
BufferedReader frBr = new BufferedReader(new FileReader(french));

while (true) {
    String partOne = enBr.readLine();
    String partTwo = frBr.readLine();

    if (partOne == null || partTwo == null)
        break;

    System.out.println(partOne + "\t" + partTwo);
}
