Because it is a custom type, custom overrides are required for the Equals () function and the hashcode () function in HashMap.Otherwise the content of the same object corresponding to the hashcode will be different, unable to play the normal function of the algorithm, covering the Equals function, should be equivalent to C + + overloaded = = operator to ensure that the equality can be judged. Except that Java does not have a custom overloaded operator

A little summary of recent projects related to CAD data1. About listIt can save a number of different elements, but how do you determine what kind of element it is when you take an element? When you take an element, you can determine what type of element is in the list by calling the GetClass method and comparing it to the class. The element is then coerced into a type cast.2.
