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 TutorialsPoint", 
            Charset.defaultCharset(), StandardOpenOption.WRITE);

         String fileContent = Files.readString(tempFilePath);

         System.out.println(fileContent);
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}
