How to construct classes in Java

Primary role: Initialize member variables (attributes)

For example:

Class Person

{

int age;

String name;

/*

Public person ()

{

}

*/Default Construction method

}

Class Person

{

int age;

String name;

public person (int age, String name)

{

Age = age;

name = name;

}

}

A method that is constructed by itself overrides the default constructed

The construction method of the class is summarized as follows:

1. The construction method name and the class name are the same;

2. The construction method has no return value;

3. The main role is to complete the initialization of new objects;

4. When creating a new object, the system automatically calls the construction method of the class;

5. Each class has a default construction method;

6. A class can have more than one construction method.
