如何仅使用其路径将txt文件转换为字符串？

with open('file.txt', 'r') as file:
    content = file.read()
    print(content)

const fs = require('fs');
fs.readFile('file.txt', 'utf-8', (err, data) => {
  if (err) throw err;
  console.log(data);
});

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

public class Main {
    public static void main(String[] args) {
        try {
            String content = new String(Files.readAllBytes(Paths.get("file.txt")));
            System.out.println(content);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
