File Class in Java

March 30, 2022 Java

In this post, you will learn how to work with the File class so that you can use that same knowledge and thus evolve.

this class provides methods for creating, deleting, getting the absolute path, and checking for a single file at a time.

`File (object).createNewFile()`	Create a file in the specified path
`File (object).delete()`	Deletion of a certain file
`File (object).getAbsolutePath()`	Gets the absolute path of the file
`File (object).exists()`	Checks if the data file exists or not

package com.caffeinealgorithm.programminginjava;

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

public class FileClass {
  private File file = new File("File.txt");

  public void Run() {
    /*
      try {
        file.createNewFile();
      }
      catch (IOException exception) {
        System.out.println(exception);
      }
    */

    file.delete();

    // System.out.println(file.getAbsolutePath());

    if (file.exists())
      System.out.println("The file \"File.txt\" exists.");
    else
      System.out.println("The file \"File.txt\" does not exist.");
  }
}

// The file "File.txt" does not exist.
