  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
