instruction executes only the current stack. While the local variable table stores the variable information required in the method, it is stored in slot, and after the operation domain is exceeded, the original memory area can be used by other local variables, like "recycle". Then, remember that Java is a static multi-dispatch, dynamic single-Dispatch language. Static dispatch, such as overloading of methods. You can determine which method to invoke by using the different parameters of the meth

special class. We can interpret an integer as an object of type int. The int type can have an assignment, addition, subtraction and other operation interfaces. The normal type can be seen as an extension of the basic type. We've seen the basic type as a data member, a parameter to a method, a method's return value, and an automatic variable inside a method . Naturally, ordinary types of objects, such as battery and torch, can also be used in these places. In the C language, the available data t

JS is a type of object-based language, he has no relationship with Java;JS Label Placement Location: 1. Inline 2. External 3. Internal;JS Code has a sequence of execution, which is different from the CSS code, when the object is not loaded or not loaded, the JS code can be run but does not take effect, so the JS code is generally placed after the The properties and methods of the JS call object are used.

, iterate, using the next method continuously until an exception is obtained, and the iterator ends. 3. Why Use iteratorsThe benefit of iterators: The iterator makes the data into memory for each time it is next. If it is a list, a large amount of memory to go into memory, the data is more likely to cause the crashLike what:The sum of the list (range (1000000)) is calculated and the data needs to be put into memory at once.In the case of iterators, using one data at a time, the first 1+2, the se

a user-defined loop object.The generator is written in a similar way to the function definition, except that the return is changed to yield. There can be more than one yield in the generator, and when the generator encounters a yield, it pauses the generator and returns the value after yield. When the generator is called again, it will continue to run from where it was just paused, until the next yield, and the generator itself forms a circulator, each cycle using a yield return value.Here is a

fork function. Although both the parent and child processes execute subsequent code, they can be distinguished by the return value of the fork, a simple example is as follows:#include Fork returns the ID of the child process to the parent process, and the child process returns 0, so the parent or child process can be distinguished by the return value.This design makes sense, although the child process cannot get the process ID by the return value, but it can get its own process ID through the G
