Java 删除文件

删除文件

要删除Java中的文件，请使用delete()方法：

import java.io.File;  // Import the File class

public class DeleteFile {
  public static void main(String[] args) { 
    File myObj = new File("filename.txt"); 
    if (myObj.delete()) { 
      System.out.println("Deleted the file: " + myObj.getName());
    } else {
      System.out.println("Failed to delete the file.");
    } 
  } 
}

输出将是：

Deleted the file: filename.txt

删除文件夹

您也可以删除文件夹。但是，它必须为空：

import java.io.File; 

public class DeleteFolder {
  public static void main(String[] args) { 
    File myObj = new File("C:\\Users\\MyName\\Test"); 
    if (myObj.delete()) { 
      System.out.println("Deleted the folder: " + myObj.getName());
    } else {
      System.out.println("Failed to delete the folder.");
    } 
  } 
}

输出将是：

Deleted the folder: Test
