A method with parameters

I. Methods with parameters

Grammar:

The access modifier method returns a value type method name (parameter list) {

Method body

Note: Split between each parameter with ","

Two. Formal parameters and arguments

Formal parameter: Parameters specified at method definition

Arguments: Parameters specified at method invocation

Three. Issues to be aware of when calling with parameter methods

1. Parameter data types for formal parameters and arguments remain consistent

2. The order of the formal parameters and arguments remains the same

3. The number of formal parameters and arguments remains the same
