Clinical documents can be revised and can be appended to existing documents. In theory, an updated document should declare that it has been deprecated, It should include a clear pointer to the new version of the document. This reduces errors or data integrity of medical service providers based on treatment decisions. However, in practice, it is impossible to ensure a clear forward pointer from an expired version to a new version. There is no trace queue that can be traced about the st

Mention Java Underwear class (Innerclass) A lot of people are not familiar with, actually similar concept in C + + also has, that is nested class (Nested Class), about the difference between the two, there will be a comparison in the following. The inner class, on the surface, defines a class in a class (as you can see from the inside class, which can be defined in many places), but it's not as simple as it might seem, and his usefulness may not be so obvious to beginners, but with his deep unde

An overview of the inner classes:The class is defined inside another class, which is called an inner class.　　Example: class B is defined in Class A, and Class B is called an inner class.Access characteristics of internal classes:　　A: Inner classes can access members of external classes directly, including private members.　　B: external

There are roughly 5 types of relationships between classes: 1, dependency relationship (Dependency) One-way, which indicates that one class relies on the definition of another class, where the change of one class affects the other class, and is a "use a" relationship If a depends on B, then B behaves as a local variable, method parameter, static method call, etc. public class Person {public void dosomething () { card = new Card ();//local variable

Internal classes are defined in Wikipedia as: In object-oriented programming, an inner class (also called a nested Class) is a class that is declared in another class or interface. The inner class differs from the subclass (subclass). (Translator Note: the wiki annotations are incorrect, and the inner and nested classes are not identical, see below.) ）In Java, the above definition can be an example of the f

The FileInputStream and FileOutputStream classes are used to create the input and output stream objects for disk files, using their constructors to specify the file path and file name. When you create an FileInputStream instance object, the specified file should be present and readable. When you create an FileOutputStream instance object, the original content in this file is overwritten if the specified file already exists. Two ways to create
