关于JAVA 初始化顺序的问题, 菜鸟刚学 JAVA 求指教
class Bowl{
Bowl(int marker){
System.out.println("Bowl(" + marker + ")");
}
void f1(int marker){
System.out.println("f1(" + marker + ")");
}
static class Table{
static Bowl bowl1 = new Bowl(1);
Table(){
System.out.println("Table()");
bowl2.f1(1);
}
void f2(int marker){
System.out.println("f2(" + marker +")");
}
static Bowl bowl2 = new Bowl(2);
}
}
class Cupboard{
Bowl bowl3 = new Bowl(3);
static Bowl bowl4 = new Bowl(4);
Cupboard(){
System.out.println("Cupboard()");
bowl4.f1(2);
}
void f3(int marker){
System.out.println("f3(" + marker +")");
}
static Bowl bowl5 = new Bowl(5);
}
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();
// 注释掉得这个内容 不知道为什么会出错 也请大神帮忙解答一下
//table.f2(1);
cupboard.f3(1);
}
// 注释掉得这个内容 不知道为什么会出错 也请大神帮忙解答一下
//static Table table = new Table();
static Cupboard cupboard = new Cupboard();
}
附上运行结果 :
Bowl(4)
Bowl(5)
Bowl(3)
Cupboard()
f1(2)
Creating new Cupboard() in main
Bowl(3)
Cupboard()
f1(2)
Creating new Cupboard() in main
Bowl(3)
Cupboard()
f1(2)
f3(1)
我表示无法理解这样的结果啊 程序不是从main开始读的么。。。 谢谢大神啊 帮忙 解释一下好不 我刚开始学 还不太懂
