The construction method of Java essay

When Java is in the new object,

First, it creates a space in memory based on the size of the class, initializing the line data

Next, the constructor method is called, and the corresponding assignment is made.

For the construction method, I have 2 words.

1, if there is an inheritance relationship, then the construction method of the parent class must be called (that is, a parent class must be produced).

2, first call the parent class construction method, and then call the subclass construction method. When the system receives our message that it wants to new a class, it first finds the parent class of the class, then finds the parent class, until the head is found, and then starts from the topmost parent class, until we have the new class.
