The argument 50 is copied into the num1 parameter.
The argument 10.25 is copied into the num2parameter.

In Java, all arguments of the primitive data types are passed by value, which means that only a copy of an argument’s value is passed into a parameter variable.
A method’s parameter variables are separate and distinct from the arguments that are listed inside the parentheses of a method call.
If a parameter variable is changed inside a method, it has no affect on the original argument.
