Stream objects created in IO Stream operations Why must I close?

Here we need to note that when we create an IO stream object in the program, and the system also creates a thing called the stream, in this case, the computer memory actually produces two things, one is the Java program class in the instance object, one is the system itself produces some kind of resources, The Java garbage collector can only manage the instance objects of the classes in the program, and there is no way to manage the resources generated by the system, so the program needs to call the Close method to notify the system to release its own generated resources.
