Java-64- Parameterized Method in Java || Java Programming смотреть онлайн

Parameterized Methods:
When parameter List is used in the method definition,then those methods are called parameterized methods.

Syntax:
return_type method_name(type p1,type p2,...){
... // method body
}

The return_type can be of any valid type even the class type we created. If the method does not return anything then we specify void to indicate that.
The Method_name can be any valid identifier except the reserve keywords & should be meaningful.

The parameter_list used to pass values to the method. The parameters are declared by type then followed by any valid para_name(p1). If contains multiple parameters then they should be separated by commas(,).

Then inside the curly braces we've the method body where the statements are written for task to be performed.

Method Declaration:
A simple method declaration as follows:

void add(int a,int b){
... //method_body
}
Method declaration or definition consists of Formal Parameters which are used into operation. The method body contains statements to perform it.

Method Call:
object.add(2,5);
The method is called with the object then the dot(.) operator followed by the method name. Here the Actual Parameters or arguments are passed as a copy to the formal parameters.
