Java 11 introduced an easy way to read and write files by providing new overloaded methods without writing much boiler plate code.
Consider the following example −
Java11Files.java
import java.io.File;
import java.io.IOException;
import java.nio.charset.Charset;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.StandardOpenOption;
public class Java11Files {
public static void main(String[] args) {
try {
// 1. Write string to sample.txt file
Path filePath = Files.writeString(
Path.of(File.createTempFile("sample", ".txt").toURI()),
"Welcome to HiTechPoints",
Charset.defaultCharset(), StandardOpenOption.WRITE);
// 2. Read text from sample.txt file
String fileContent = Files.readString(filePath);
System.out.println(fileContent);
} catch (IOException e) {
e.printStackTrace();
}
}
}
Output
Welcome to HiTechPoints
