The readString() method of File Class in Java is used to read contents to the specified file.

Syntax:

Files.readString(filePath)

Parameters:

path - File path with data type as Path

Return Value: This method returns the content of the file in String format.

Below are two overloaded forms of the readString() method.

public static String readString(Path path) throws IOException

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
 
public class GFG {
    public static void main(String[] args)
    {
        // creating path
        Path filePath
            = Paths.get("/home/mayur/", "temp", "gfg.txt");
        try
 
        {
            // reading file from given path
            String content = Files.readString(filePath);
            // printing the content
            System.out.println(content);
        }
        catch (IOException e) {
            e.printStackTrace();
