How To Create a File in Java

This example will show you how to create a new file in Java.

To do this, we use the File.createNewFile() method.

The method returns a boolean value:
- true - The file has been successfully created.
- false - The operation failed or the file already exists.

import java.io.File;
import java.io.IOException;

public class CreateFileExample
  {
    public static void main( String[] args )
     {
        try {

            File file = new File("c:\\project\\newfile.txt");

            if (file.createNewFile()){
              System.out.println("File ‘newfile.txt’ is created successfully!");
        }

        else{
            System.out.println("File ‘newfile.txt’ already exists.");
            }

        }
        catch (IOException e) {
        e.printStackTrace();
        }
