Initialization of a classin the initialization phase, the Java virtual machine executes the initialization statement of the class, giving the initial value to the static variable of the class. In a program, there are two ways to initialize a static

Recently in looking at high concurrency, suddenly see the role of static sometimes very powerful, I went over it:static denotes "global" or "static" meaning, used to decorate member variables and member methods, or to form static-code blocks, but

first, define a Class A as follows Class A { static int a = 1; static int b = 2; public static void PrintA () { System.out.println (a); } public static void Printb () { System.out.println (b); } } Class A

Static variables exist only in the scope of the function, the static variable only exists in the stack, the next time the function is called, the value of the variable will be preservedStatic variables exist only within the scope of a function, and

1. First and foremost, the first and most important one: hide. (static function, static variable all can)When you compile multiple files at the same time, all global variables and functions that have no static prefix are globally visible.For example,
