class Bowl {

}
void f(int marker) {
System.out.println("f(" + marker + ")");
}
}
class Table {

}
void f3(int marker) {

}
public class StaticInitialization {
public static void main(String[] args) {
System.out.println(
"Creating new Cupboard() in main");
new Cupboard();
System.out.println(
"Creating new Cupboard() in main");
new Cupboard();
t2.f2(1);
t3.f3(1);
}
static Table t2 = new Table();
static Cupboard t3 = new Cupboard();
}
运行结果：
Bowl(1)
Bowl(2)
Table()
f(1)
Bowl(4)
Bowl(5)
Bowl(3)
Cupboard()
f(2)
Creating new Cupboard() in main
Bowl(3)
Cupboard()
f(2)
Creating new Cupboard() in main
Bowl(3)
Cupboard()
f(2)
f2(1)
f3(1)
问：为什么不先打印Creating new Cupboard() in main 这句话啊？？
