the Java Authoritative Technical Manual (6th edition) (Java ina nutshell). He has delivered several lectures on the Java platform, performance, concurrency, and related topics. Ben Evans Q: The Java authoritative technical manual (java in a nutshell) is a classic, its previous version (5th edition) up to 1200 pages, and 10 years later in China will be published in the 6th edition is only 400 pages, what i

number of processes is greater than the number of CPUs, you still need To use concurrency technology. In Windows, CPU allocation is done in threads, and a process may Made up of multiple threads, the situation is more complex, but in a nutshell, the following relationships are: Number of bus Number of bus threads > number of CPUs: concurrently running The efficiency of parallel operation is obviously higher than that of concurrency, so the efficiency

memory are allocated from here." The heap is created when the Java virtual machine is started. "" The memory outside the heap in the JVM is called non-heap (non-heap memory) ". You can see that the JVM primarily manages two types of memory: heap and non-heap. In a nutshell, a heap is a Java code-readable memory that is left to the developer, not a heap, which is left to itself by the JVM, so the method area, the JVM internally processes or optimizes

C + + polymorphism is summed up in a nutshell: By adding the virtual keyword to a function in the base class, overriding the function in a derived class, the runtime will invoke the corresponding function based on the actual type of the object. If the object type is a derived class, the function of the derived class is called, and if the object type is a base class, the function of the base class is called1: A function declared with the virtual keywor

on the drive. RB indicates read binary, and + indicates that write can be performed in addition to read. 23 rows Buff [0] =0xac; Therefore, if you want to merge a byte with the value 0 x AC, first declare the buff char array and enter 0 x AC. 25 rows Fseek (FP,0x33, Seek_set ); Use fseek to move the location of binary file to 0x33. seek_set indicates that the offset starts from the beginning. 26 rows Fwrite (buff,Sizeof(UnsignedChar),1, FP ); Use fwrite to merge the buff into

, the program will go to the next "case ". If this "case" is the last one, then there will be no problem. If there is a "case" behind it, it will seem insecure.Error example:Switch (I ){Case 1:X = 10;Break;Case 2:X = 20;Default:A = 40;Break;Correct:Switch (I ){Case 1:X = 10;Break;Case 2: // ViolationX = 20;Break;Default:X = 40;Break; (8) do not use 'System. getenv ()'We do not recommend using 'System. getenv () '. This method looks very useful, but not all systems have environment variables. Thi
