如何进行质量分配

Question

如何为变量堆栈进行质量分配？

我声明了变量列表

String not_id, not_section, not_steet, not_sqTotal, not_sqLiving, not_sqKitchen, not_flat, not_floor, not_floors, not_text, user_phone1, user_phone2, user_contact, not_region, not_district, not_settle, not_price, not_photo, not_date, not_date_till, not_up, not_premium, not_status;

我希望它们中的所有内容都等于"" - 空字符串（或"a"，只是一个例子并不重要）

Answer 1

not_id = not_section = ... = not_status = "";

Answer 2

String not_id, not_section, not_steet, not_sqTotal, not_sqLiving, not_sqKitchen, not_flat, not_floor, not_floors, not_text, user_phone1, user_phone2, user_contact, not_region, not_district, not_settle, not_price, not_photo, not_date, not_date_till, not_up, not_premium, not_status;

not_id = not_section = not_steet = not_sqTotal = not_sqLiving = not_sqKitchen = not_flat = not_floor = not_floors = not_text = user_phone1 = user_phone2 = user_contact = not_region = not_district = not_settle = not_price = not_photo = not_date = not_date_till = not_up = not_premium = not_status = "";

Answer 3

String not_id=not_section=not_steet=not_sqTotal=not_sqLiving=not_sqKitchen=not_flat=not_floor=not_floors=not_text=user_phone1=user_phone2=user_contact=not_region=not_district=not_settle=not_price=not_photo=not_date=not_date_till=not_up=not_premium=not_status="a";

Answer 4

具有for循环的数组或其他集合。你能想到的任何解决方案都会减少到这一点。如果属于数组的值不是同类的，则每个变量必须有一个您希望实际分配给某个值的赋值。没有办法解决这个问题。

通常，如果您希望将所有对象初始化为复杂的东西，您可以使用默认构造函数创建一个包装类，该构造函数将其封装起来，但在您的情况下，这将更加有用。 e.g。

Foo a = new Foo(1, 2, 3);
Foo b = new Foo(1, 2, 3);

可以替换为

Foo a = new FooW();

FooW使用调用Foo的默认构造函数扩展super(1, 2, 3)。

Answer 5

循环

for (String s: list) {
            s=""; 
            //or 
            s="a";
        }
