Easily load the entire contents of a file into a single string variable in Java.

Java

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path; public class FileToString { public static void main(String[] args) throws IOException { String content = Files.readString(Path.of("file.txt")); System.out.println(content); }
}

Yeah, since Java 11 you can just use Files.readString(path) - super clean, no loops or streams needed. If you're on an older version, new Scanner(file).useDelimiter("\\Z").next() does the trick in one line too.
