Java 删除文件

删除文件

要在 Java 中删除文件，请使用 delete() 方法:

实例

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.");
  }
 }
}

  if (myObj.delete()) {
   System.out.println("Deleted the folder: " + myObj.getName());
  } else {
   System.out.println("Failed to delete the folder.");
  }
 }
