Tutorial On Parametrized Methods In Java

Before reading this tutorial you should read Tutorial on method in java for better understanding of parametrized method in java.

PARAMETRIZED METHOD:

Method that is used to for passing information to a  using parameters is called parametrized method for passing a information using method require two things first is type and second is variable name such as String n.Any type of data can be used as a parameter in  in method such as integer,double and float.Array and object can also be used as a parameter as shown in below.

{
String name,editor;
float prize;
int quantity;

void input(String n,String e,int q,float p)
{
name=n;
editor=e;
quantity=q;
prize=p;
}
void output()
{
System.out.println("Book Name= "+name);
System.out.println("Editor= "+editor);
System.out.println("Quantity= "+quantity);
System.out.println("Prize= "+prize+"$");
System.out.println();
}
}
class bookmain
{
public static void main(String arg[])
{
book information=new book();
information.input("Electronic Devices","Robert Boylestad",4,60);
information.output();
information.input("Electric Circuit","F.Bogart",10,35);
information.output();
information.input("Business","Ronald J.Ebert",2,15);
information.output();

}
}

OUTPUT:
