-# Methods
-
-## What are methods
-
-A java method can be interpreted as a subprogram. It is a collection of statements taht are grouped togehter to perform an operation
-
-## Built- in vs User-defined Methods
-
-**Built-in:**
-
-Built-in methods are part of the complier package such as `System.out.println`
-
-**Function (return) - Type:** it calcualtes and return a value
-```java
-public static int calculate(int number){
-    return 1;
-}
-```
-
-**Procedure-type:** executes some commands
-
-**Function (return)- type:** 
-```java
-public static return type method-name (parameter 1)
-```
-
-**Procedure-type method:**
-
-```java
-public static void method-name (paramenter 1)
-```
-## How to create a method
-
-In general, method declarations has 5 basic components:
-- **Modifier:** defines access type of the method i.e. from were it can be accessed in your application (For example: public)
-- **The return type:** the data type of the value returned by the method or void if it does not return a value (procedure and function type)
-- **Method name:** a specific names that identifies the method that  can be used to invoke it later
-- **Parameter list:** Comma separated list of the input parameter are defined preceded with their data type, within the enclosed parentheses, If there are no parameters, you must use empty parentheses()
-- **Method body:** It is enclosed between braces. the code that you need to be execute to perfrom your intended operations
-
-```java
-public int max(int x, int y) {
-    if(x > y) {
-        return x;
-    }
-    return y;
-}
-```
-
-## How to call a method (method invocation
-
-To invoke a method you need the method name with the parameter list defined between parentheses
-
-**Exammple:**
-```
-Method Name (paramter list)
-```
-Must have () parentheses when calling a method, even with no passing parameters
-
-## Pass-By-Value
-**What happens:** When a method is called, a copy of the value of each argument is passed  to the method
-
-**In the second method:** This copy can be changed inside the method, however such a change has no effect on the actual argumnet
-
-```java
-int num=10;
-double decimal = 5.2;
-NumberManeuvers(num decimal);
-System.out.println("num = " + num + "and decimal = " + decimal);
-
-public static void numberManeuvers(int i, double j) {
-    if(i == 10) {
-        j = 6.2;
-        i = 12;
-    }
-}
-// output: num = 10 and decimal = 5.2
-```
-
-## Pass-By-Reference
-**What happens:** When an object (Array, String) is passed to a method, its memory location address (rreference point) is used
-
-**The object:** Arrays & trings behave like objects
-
-**In the second method:** When their memory location is passed to the method the oject can be manipulated in the method resulting in actual changes to the object (Array, String)
-
-```
-int [] nums = {1, 2, 3};
-testingArray(num);
-System.out.println("num[0] = " + num[0] + ", num[1] = " + num[1] + ", num[2] = " + num[2]);
-
-public static void testingArray(int[] value) {
-    value[0] = 4;
-    value[1] = 5;
-    value[2] = 6;
-}
-}
-```

-## Benefits to methods
-There are many advantages of using methods. Some of them are listed below:
-- It makes the program well structured
-- methods enhance the readability of the code.
-- It provides an effective way for the user to reuse the existing code.
-- Allows for easier debugging.
