This article mainly introduces what the member method of java is, which can be used for reference by interested friends. I hope you can learn a lot after reading this article. Let's take a look at it.

Definition of member method:

When the member method name consists of multiple words, the second word begins with an uppercase first letter.

Return value: refers to the data content returned from the body of the method to the outside of the method.

Return value type: mainly refers to the data type of the return value, which can be a basic data type or a reference data type.

The return keyword in the body of the method returns the specific data content and ends the current method.

If the method does not need to return any data, the return value type is void.

Formal parameters: mainly bring the data from outside the method into the body of the method.

Formal parameter list refers to a list composed of multiple formal parameters. If you don't need it, you don't have to write it. The syntax format is as follows:

Data type parameter name 1, data type parameter name 2.

The member method body mainly writes the statement block of the method function in seconds.

"Note: member variables and member methods are members within the class, so member methods can access member variables directly."
