Java method Overloading

Java method Overloading

Class ChongZai {

Public void a (int );

Public void a (Strting );

Public void a (int a, int B );

}

 

The above is an overload, and the overload must meet the following conditions:

1. Must beSame class

2.The method name (or function) is the same.

3.The parameter type is different or the number of parameters is different.

 

The role of overload:

Or the above example

ChongZai cz = new ChongZai ();

Cz. a (1); // call a (int );

Cz. a ("passed parameter"); // call a (String)

Cz. a (1, 2); // call a (int a, int B)

 

Which method is called, and the program determines which method to call based on the parameters you enter.

 

 

Reload functions:

 

For example, if you are playing a game, you may be able to have multiple people complete the game. If you are not sure that you are a few people, you can use the heavy load.

For example, you can define up to three parameters.

Public void a (String );

Public void a (String a, String B );

Public void a (String a, String B, String c );

 

For two people, you can call the two parameter methods. For three people, you can call the three parameter methods.
