Reading a string below a string from a file

Question

For example, I were to save contact details on a .txt file and after that is saved, I would want to view the contact details of the person only by entering the name.

For example, if I were to have a .txt file containing these strings,

Name: Shiroe
Contact Number: 1234567890
Name: Kirito
Contact Number: 0987654321

and I entered "Shiroe" as the contact name to be viewed. My expected output would be,

Name: Shiroe
Contact Number: 1234567890

So, bottom line, is it possible to read a string below a string (read "Shiroe"/"Name: Shiro" first and then reads the line below/after "Shiroe") to use as an output? Or am I asking the wrong question?

You could do something like this... It's hard to mock a correct snippet without any code of yours shown, but the logic should apply...

try(BufferedReader br = new BufferedReader(new FileReader("yourFile.txt"))) {
        StringBuilder builder = new StringBuilder();
        String line = br.readLine();
        Boolean needNextLine = false;

        while (line != null) {
            if (needNextLine) {
                sb.append(line)
                needNextLine = false;
                sb.append(System.lineSeparator());
            }

            if (line.contains("Shiroe")) {     // hardcoded
                 sb.append(line);
                 needNextLine = true;
                 sb.append(System.lineSeparator());
            }

            line = br.readLine();
        }
        String toBeReturned = sb.toString();
    }
