later:constructorconstructor is the constructor, but unlike class's Newinstace method, constructor's newinstance (Object ... initargs) is varargs, which is the three point mentioned above. Parameters can be passed in. The interesting point is that the constructor array is ordered, as long as your constructor is written in front of the class, and if there are other methods before it, then the order of the arrays is not sorted by rank.The function of reflection is to check the type of object at r

code specified for the ASM segment. the ANSI C specification uses the keyword __asm__ to replace the keyword ASM when using inline assembly statements, because the ANSI C keyword ASM is used for other purposes. as follows: __asm__ ("Addl $, result\n\t" "Subl $, result\n\t");The Basic ASM format provides a simple style for creating assembly code, but there are some limitations. First, all input and output values must use the global variables of the C program, as seen in the example abo
