File Write Read

A small text file can be written, read back, and removed using Files helpers.

FileWriteRead.java

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

public class FileWriteRead {
    public static void main(String[] args) throws Exception {
        int score = ;
        Path path = Path.of("java21_write_read.txt");
        String text = "score=" + score;

        Files.writeString(path, text);
        String loaded = Files.readString(path);
        Files.deleteIfExists(path);

        System.out.println(loaded);
    }
}

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

public class FileWriteRead {
    public static void main(String[] args) throws Exception {
        int score = ;
        Path path = Path.of("java21_write_read.txt");
        String text = "score=" + score;

        Files.writeString(path, text);
        String loaded = Files.readString(path);
        Files.deleteIfExists(path);

        System.out.println(loaded);
    }
}

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

public class FileWriteRead {
    public static void main(String[] args) throws Exception {
        int score = ;
        Path path = Path.of("java21_write_read.txt");
        String text = "score=" + score;

        Files.writeString(path, text);
        String loaded = Files.readString(path);
        Files.deleteIfExists(path);

        System.out.println(loaded);
    }
}

writeString Files.writeString stores text at a path, creating or replacing the file.

readString Files.readString loads the whole text file into a String.
