How to convert a char (in the form of a character) to a string in Java?

Question

Java

I am using FileReader to read from a file. Using this class, you can read information character by character. The read() method reads a character from the file, but returns it as an int. And how to get the character itself from this character code and write it to string?

Answer 1

public class App {
    public static void main(String[] args) throws FileNotFoundException {
        try (FileReader in = new FileReader("c://file.txt")) {
            String value = new String(new char[] { (char) in.read() }); // Первый символ из текстового файла
        } catch (IOException err) {
            err.printStackTrace();
        }
    }
}

Answer 2

Thank you all for your efforts. I figured out what my problem is. I missed a little. I did not set the type char to the variable into which I write the data from the file. I had int. Therefore, he wrote the codes to me in a line.
