To understand the use of super, you first know that super is used to call the base class (the parent Class).1.super. A method or variable of the parent class that invokes the parent class's method or variable in the subclass.2.super (parameter) is used to invoke a constructor that has the same parameters in the parent class.The main thing is that super is used to refer to the parent class.Use of Abstract:1. The addition of abstractions to a class or method constitutes an abstract class or abstra

operator in the statement that creates the object, and a class can have more than one constructor, and the lesson is differentiated by the number of arguments or by the difference in the parameter type.Constructs an object, calling its constructor first to initialize its member functions and member variables. Child classes have member variables and member methods of the parent class, and the member variables and member methods inherited from the parent class are not properly initialized.cannot

Given a variable t of the parameterized type T, the Statement t = NULL is valid only when T is of the reference type; only when T is of the numerical type rather than the structure, statement t = 0 can be used normally. The solution is to useDefaultKeyword. This keyword returns NULL for the reference type and zero for the valu

There are three types of computer parallel processing technology: time parallel, space parallel, time parallel + space parallel. Programs and data are stored in main memory, and main memory usually uses multi-body interleaved memory to improve access speed. the cache is a cache buffer that compensates for the dif
