Java Code to Read complete file without using loop

In Java 8, you can use the Files.readAllBytes() method to read the entire contents of a file as a byte array, and then convert it to a string using the new String() constructor.

Here’s an example code that demonstrates how to read a complete file without using a loop:

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

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

In this example, we use the Files.readAllBytes() method to read the entire contents of the file as a byte array. Then, we create a new string object by passing the byte array to the String() constructor. Finally, we print the contents of the file to the console.

Approach2:

List<String> lines = Files.readAllLines(Paths.get("file"), StandardCharsets.UTF_8);
