Java Construction code block

One: Overview

Function: initializes the object.

Precedence: Executes prior to the object's constructor.

{

/* Construct code block code */

}

Uniform initialization of all objects, and constructors simply initialize specific objects, because constructors can be overloaded, resulting in different constructors, but building blocks of code will be executed when an object is established.

Two: procedure

The main function, stating that there are two objects being created, and the tangent constructors are different.

　　

The specific object.

　　

III: Results

　　

The construction code block is always executed before each object's constructor.
