How to read data from file till I encounter an empty line

Question

Is there a way I can read multiple lines from a text file until I encounter an empty line?

For example my text file looks like this:

text-text-text-text-text-text-text-text-text-text-text-text-text-text-text-text

//This is empty line

text2-tex2-text2-tex2-text2-tex2-text2-text2

Now, I want to input text-text... till the empty line into a string. How can I do that?

check below code, 1st i have read all the lines from text file, then i have check whether file contains any blank line or not, if it contains then i break the loop.

A.text

text-text-text-text-text-text-text-text-text-text-text-text-text-text-text-text

text2-tex2-text2-tex2-text2-tex2-text2-text2

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

public class Test {
    public static void main(String args[]){
        try (BufferedReader br = new BufferedReader(new FileReader("E:\\A.txt"))) {
            String line;
            while ((line = br.readLine()) != null) {
                if(!line.isEmpty()){
                    System.out.println(line);
                } else {
                    break;
                }
            }
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
}
