Today’s Java learning tips

1.Constructor don’t have a return type!

2.Child’s constructor must call super() first,if they don’t call it manually, the compiler will call it automatically. But if you call super() int a wrong order. It won’t work.

3.in a constructor ，we could use this（） to call a overloaded constructor, but we can only use either this() or super() because this() is another constructor who will also call super().

4.If a reference to a object is alive, the object is alive too, and vice versa.

5.Local variables only live in the method who declare it. Instance variables would not die until the object is dying.

6.When a reference is assigned null, the object linked to it will be destroy by GC

7.static method is called through Class,not a instance. That is because static method do not rely on any instance variable.

8.static variable is shared by all the instances of the Class.

9.final static variable is a constant, it could be initialized when declare or static initializing.

10. final variable can not be changed after initializing; final class can not be inherited and final method can not be override.

11.Constant usually use all CAPITAL WORDS, like PI.
