Java MCQ: What does the Files.readString() method in Java 11 return?

Answer:

Explanation:

The Files.readString() method, introduced in Java 11, reads the content of a file and returns it as a single string. This method simplifies reading text files by providing a straightforward way to obtain the entire content of a file as a string, without the need to manually handle streams or readers.

Here’s an example of using Files.readString():

import java.nio.file.Files;
import java.nio.file.Path;

public class FilesReadStringExample {
    public static void main(String[] args) throws Exception {
        Path filePath = Path.of("example.txt");
        String content = Files.readString(filePath);
        System.out.println(content);
    }
}

In this example, Files.readString(filePath) reads the content of the file example.txt and returns it as a single string, which is then printed to the console.

The Files.readString() method is particularly useful when you need to quickly read the content of a text file into memory for processing or display.
