Section 8.2 Creating Files

We will now create a File object. It is important to create a meaningful name for the File object. We will call ours myFile, and we will call our class CreateFileObject. Listing 8.2.1 shows the code to create a File object in Java.

Now let’s learn how to make a file in Java. In Python. files can be made using the open() function on a file path that doesn’t exist yet. Similarly, in Java you create a file by using the createNewFile() method on a File object. This method actually does the work of creating a file and saving it in the current working directory, and returns a boolean value of either true or false if the file is successfully created. We can use this method’s possible return values in tandem with an if/else selection to determine if the file was created. Finally, we encase this code within try/catch blocks. This step is required in the Java code to be compiled. If try/catch blocks using IOException are not included, there will be compilation errors.

Listing 8.2.3 shows the equivalent code to create a file in Python.

Listing 8.2.4 shows the equivalent code to create a file in Java.

import java.io.File;

---
import java.io.Scanner;
 #paired
---
public class CreateFile {
     public static void main(String[] args) {

---
        File myFile = new File("myfile.txt");

---
        File myFile = new File();
 #paired
---
        System.out.println(myFile);

---
    }
 }
