In Java 11, a new method called **`readString`** was added to the `java.nio.file.Files` class to read all content from a file into a string. 

This method closes the file once the file is read or any exception is thrown during execution, so we don't need to worry about closing the file.
 
There are two overloaded methods: 

```
1. public static String readString​(Path path) throws IOException
 
2. public static String readString​(Path path, Charset cs) throws IOException
```

Using the first method, we can read the file with the "UTF-8" `Charset`.

The second method is used to pass a specific `Charset` like US_ASCII.

# Example 


import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.Files;
import java.io.IOException;

class Main {
    public static void main( String args[] ) {
        Path filePath = Paths.get("./test.txt");
        try {
            String fileContent = Files.readString(filePath);
 
            System.out.println(fileContent);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

In the code above, we have: 

* Created a text file with the name `test.txt`.

* Created the `Path` object pointing to the created text file.
 
* Read the content of the file using the `Files.readString` method and stored the return file content string to `fileContent` variable.

* Printed the file content to the console.

What is Files.readString in Java?

Java 11's Files.readString method reads file content into a string while handling file closure automatically.
