Java Properties.load() - how to switch key value pairs?

Question

I need to read in a Properties object from a file, however I need to switch the key and value pairs around, ie I need the keys to become the property values and vice-versa. I also cannot just change this on the file I am reading in. Any ideas how I could do this?

Thanks

Answer 1

您可以创建第二个Properties对象，遍历刚刚读过的entires，调用put(entry.getValue(), entry.getKey())然后就可以了。

Answer 2

寻找这个Properties.store（）
