三、静态代码块 虽然静态代码块和main()方法都被static修饰,但静态代码块通常用来初始化一些静态变量,它会优先于 main() 方法执行。来段代码感受一下: 【代码示例】 publicclassTest{ publicstaticvoidmain(String[] args){ System.out.println("main 方法"); } static{ System.out.println("静态代码块"); }...
public class AsyncStaticMethodCall { public static void main(String[] args) throws ExecutionException, InterruptedException { CompletableFuture<String> future = (() -> { //这是你要异步调用的静态方法 return (); }); //在这里继续执行其他任务,而异步方法将在后台运行 ("Continuing with other tasks....
} static void Main(string[] args) { Console.Write(Program.i);//结果为2,首先,类被加载,所有的静态成员被创建在静态存储区,i=0,接着调用了类的成员,这时候静态构造函数就会被调用,i=2 Program p = new Program(); Console.Write(Program.i);//结果为1,实力化后,调用了实例构造函数,i=1,因为静态...
