feat: Add ParametersArguments class to demonstrate method parameters and arguments

Add a program that:
- Defines a user-defined method `addNumbers` with parameters
- Passes arguments to the method and returns the sum
- Demonstrates basic usage of method calls, parameters, and return values in Java.

 /* In Java, parameters are the variables listed in the method definition.
 
-They act as placeholders for the values that the method can accept. For example, in the method:

+For example, in the method:
 
-public static int addNumbers(int a, int b)
-{
+public static int addNumbers(int a, int b) {
     return a + b;
 }
 
-Here, a and b are parameters. They define what kind of values the method addNumbers can accept (in this case, two integers).
-
-When you call the method, you pass arguments (actual values) to these parameters. For example:
+Here, a and b are parameters.

 Here, 3 and 5 are arguments passed to the parameters a and b.
 
 In short:
-
 Parameters are defined in the method signature.
 Arguments are the actual values passed to the method when it is called.
 
 Parameters:
-
 Defined in the method signature.
 Act as placeholders for the values the method will receive.
 
 Example: In public static void greet(String name), name is a parameter.
 
 Arguments:
 The actual values passed to the method when it is called.
-
 Example: In greet("Alice"), "Alice" is an argument passed to the name parameter.
 
 Key Difference:
 Parameters are part of the method definition (what the method expects).
 Arguments are the actual values you provide when calling the method.
-
 addNumbers(3, 5); → This is a method call that invokes the addNumbers method.
 
 call it a "Method Call" or "Method Invocation
