Step-by-step explanation
Parameter is basically a variable which is defined by a method/function.
When a method/function is called then this Parameter receives the value.
In any method/function, Parameter works as recipient.
If we pass a value In a method/function when it invokes then that value is
called Argument.In any method/function, Argument works as agent.
Example:
// here p1 and p2 are parameters in the method
fun test(p1,p2)
{
return p1+p2;
}
// here 2,6 are Argument in the method
test(2,6);
