还是没有高清楚
class B
{
static int a = 0;
{
System.out.println("B.scope is running");
a = 10 ;
}
static
{
System.out.println("B.static scope is running");
a = 20;
}
public B()
{
System.out.println("B.Constructor is running");
}
public static void main(String arg[])
{
System.out.println(B.a);
System.out.println(B.a);
B b1 = new B();
B b2 = new B();
System.out.println(b1.a);
System.out.println(b2.a);
System.out.println(B.a);
}
}
static int a 和static 后面怎么能跟方法是什么用法呢？
