Java Create File example

FileOutputStream class

At a condition where you want a create and write data into a file using FileOutputStream.write() method automatically creates a new file and writes content to it.

See the below example of Java create a text file.

import java.nio.file.Paths;

public class FileCreating {

    public static void main(String[] args) {
        String content = "EyeHunt data";

        try {
            Files.write(Paths.get("newFile.txt"), content.getBytes());
        } catch (IOException e) {

How to Java create a file in the directory

String path = "C:" + File.separator + "hello" + File.separator + "hi.txt";
// Use relative path for Unix systems
File f = new File(path);


Conclusion: Some Points you should be in mind when creating a file in java.

  • Check the file if exists or not then create it.
  • Write Program with exception Handling to prevent an application crash
  • Close the file stream after use to release all resources.
