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
