This topic is about Java 11 – File APIs.
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 −
ApiTester.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 APITester {
public static void main(String[] args) {
try {
Path tempFilePath = Files.writeString(
Path.of(File.createTempFile("tempFile", ".tmp").toURI()),
"Welcome to Adglob",
Charset.defaultCharset(), StandardOpenOption.WRITE);
String fileContent = Files.readString(tempFilePath);
System.out.println(fileContent);
} catch (IOException e) {
e.printStackTrace();
}
}
}
Output
