[Deep Dive into the. NET platform] talking about the. NET Framework primitive type,. netframework What is a primitive type? Beginners may have seldom heard of this term, but the most commonly used is the primitive type. Let's take a look at the following two lines of code: System.Int32 a = 5;int a = 5; Both the above two lines of code declare an int type variable, but we usually use the second method whe

The second kind of IDE looks for links, which refers to automatic compilation, excludes unused classes, but excludes the SDK.The third is to exclude class libraries that are not used in all assemblies.Note: For serialization and the underlying use of serialization, the link cannot be found and may be excluded from the use of the class, resulting in the program not being used.Workaround:You can exclude assemblies that you do not want to link.What effect does thin body have?I did not

to set the capacity to the maximum possible length of the string, ensuring that StringBuilder does not need to allocate memory repeatedly.If the character's capacity exceeds the set maximum capacity, the. NET runtime automatically allocates memory and doubles.For our. NET programmers, the difference between StringBuilder and String is that the StringBuilder can display the settings to allocate the size of the memory,A string can only be allocated enough memory by the system based on the size of

Deep-Dive Java Virtual machine--JVM memory

can also cause outofmemoryerror anomalies.The new nio=new Input/output class was added to JDK 1.4, introducing a channel-and buffer-based IO approach, which can allocate out-of-heap memory directly using local functions. The data in the out-of-heap memory is then manipulated using a Directbytebuffer object stored in the heap as a reference to this memory. This can significantly improve performance in some scenarios because it avoids copying data back and forth in the Java heap and the native he

Recurrent neural networks deep dive

A recurrent neural network (RNN) is a class of neural networks that includes weighted connections within a layer (compared With traditional Feed-forward networks, where connects feeds only to subsequent layers). Because Rnns include loops, they can store information while processing new input. This memory makes them ideal for processing tasks where prior inputs must to considered (such as time-series data). For this reason, the current deep learning n
