java从文件夹中删除文件

Question

I am trying to delete a file: This is the code and I can't see anything wrong

System.out.println("users//"+"user"+i.getId());
            File f=new File("users//"+"user"+i.getId());
            System.out.println("Can READ: "+f.canRead());
            System.out.println("Can WRITE: "+f.canWrite());
            System.out.println("Can EXEC: "+f.canExecute());
            System.out.println("Exists: "+f.exists());
            System.out.println(f.delete());

Yes, I have the right to read,write,exec and the file exists. I don't have any exceptions

Answer 1

I have tried this code and it works:

public static void main(String[] args) {
        try {
            File file = new File("c:\\Users\\Akhil\\logfile11052015.log");
            if (file.delete()) {
                System.out.println("Success: " + file.getName() + " is deleted!");
            } else {
                System.out.println("Failed: Delete operation is failed.");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

May be you can check if you are providing correct path in your case and file exists there.

Output: Success: logfile11052015.log is deleted!

删除后，我需要调用System.gc() 。
