method that does not have the subclass itself, and the parent class has and can inherit (that is, not private). You can extend the functionality of overridden methods in a subclass by super referencing the method of the parent class when overriding the method of the parent class. Hiding is called based on the type of reference (called static methods and member variables), and overrides are called based on the type of object. All of this is based on a very important principle in

For example, the following: Public class sample3_14{ publicstaticvoid main (string[] args) { int i = n; long L = >>; System.out.println ("i =" + i); System.out.println ("L =" + l);} } According to our normal understanding of the shift operation, the 32-bit integer value 88 is shifted left 32 bits, the entire bit pattern is displayed as 0, so the final result is 0, but in the final result I will find that the valu

with each other and synchronize behavior-especially with regard to the use of shared variables. In addition, the IPC and synchronization mechanisms enable threads to communicate with each other.? The main advantage of threading is that it is easier to share data between threads, and for some algorithms it is more natural to implement multi-threading than to implement multiple processes. Furthermore, it is obvious that multithreaded applications can benefit from parallel processing of multiproce
