Cause tracking and resolution:1. Access to the data found that the use of @override under the jdk1.5 annotation must ensure that the method being labeled is derived from class rather than interface.2. Even if your JDK is 1.6, you will need to modify the compiled JDK version in MyEclipse and change from 1.5 (5.0) to 1.6 (6.0), or else the above error may occur.Liberation method: Under MyEclipse: Windows-preferences-java Compiler, on the right of the Co

A, what is method overloading? (in the same Class) method overloading refers to the case where the same method name appears in the same class, with a different argument list.B, what is method coverage? A method override in a child-parent class is a function that runs a subclass when a method declaration is identical to the parent class, which is called a overwrite operation.Method overrides occur between the parent class and the subclass with the inhe

Bluetooth bluetooth® technology is widely used in a variety of devices, and will continue to play a key role in the IoT world of IoT. Here are some tips on Bluetooth technology to prepare for reference.Bluetooth bluetooth® Technology was founded in 1994 with the name of a Danish king Harold Bluetoothin 10th century, wh

this point, the function of the base class is hidden, regardless of the virtual keyword (Note that it is not confused with overloading).(2) If the function of the derived class has the same name as the function of the base class, and the parameters are the same , the base class function does not have the virtual keyword. At this point, the function of the base class is hidden (be careful not to confuse the overlay).Cases:#include using namespacestd;classbase{ Public: Virtual voidFfloatx) {co

Overload: Implements multiple versions of a function. The Compiler determines when to call a function. The return value of a function is not used as a basis to distinguish between overloaded functions. Override: implements the same function as the parent class signature in the subclass. Overloading is when you make multiple versions of a function. The Compiler figures out which function to call. Overloading does not take return type to differentia

I. The role of IsEqual The role of isequal: To determine whether two objects are equal For the base type, the = = operator compares the value;For object types, the = = operator compares the address of an object (that is, whether it is the same object) Objective-c and Java do not support operator overloading, and C + + supports operator overloading, so that you can make a judgment on operator overloading Two, rewrite the IsEqual method The type defined in the COCOA framework,NSString isequaltost
