Which class in Java is used to create a new directory?OptionsFileWriterFileReaderFileDirectory

The class used in Java to create a new directory is the File class. Here are the steps to do it:

1. First, import the File class from the java.io package at the beginning of your Java program. Like this:

import java.io.File;

2. Create a new File object and pass the directory path to the constructor. Like this:

File directory = new File("directoryPath");

3. Use the mkdir() or mkdirs() method of the File object to create the directory. The mkdir() method creates the directory named by this abstract pathname, whereas mkdirs() creates the directory named by this abstract pathname including any necessary but nonexistent parent directories. Like this:

boolean isCreated = directory.mkdir(); // or directory.mkdirs();

4. Check if the directory is created successfully. The mkdir() and mkdirs() methods return true if and only if the directory was created; false otherwise. Like this:

if(isCreated) {
    System.out.println("Directory created successfully");
} else {
    System.out.println("Failed to create the directory");
}

So, the correct answer to your question is: File.
