C-language dummies (1): nested loops-program structure, dummies Loop statement nesting a loop structure can contain another loop, called loop nesting, or multiple loops. The nested loop is a double loop.

Static variable statics in PHP and Java Because static members are created when the class is first loaded, it is possible to use the class name to access static members that do not require objects outside of the class, and static members are shared by each instance object of the class, so can we use objects in our PHP language to access static members of the class?Static members do not exist within each object, but each object can be shared, so if w

, the instructions are executed sequentially in the logic or one line, so the memory is first allocated for the static int I, and the default value of int in that memory is 0, then the static int num variable is allocated memory, and the value is of course 0.Then take the second step, assign a value to the variable: first assign the static int i variable, i=getnum (), see the code inside the Getnum, that is, return num, this time num value is 0, so I is 0. The variable num is then assigned a val

So one output is tttt, no problem.The static statement block for the 6.X class executes, so it's time to execute the main () method.7.new Z (); This method is executed. 8. Since new Z (), then the Z class will be loaded. Because the Z class inherits the X class. So you have to load the X class before you can. Because the X class has already been loaded. So there is no need to load the X class at this time. Z class loads the static statement block to ex

Okay. let's talk about this in this section.
