1. Writing Methods

2. Create the method A Method is a tool to do something
It contains the code that performs the job
Methods have two parts

3. Create the method The first part is called the Header
modifier return name
public void message( ) {
open & closing braces }

4. Methods have two parts The second part is called the Body
The body contains the lines of code that instruct the computer what to do
You can have as many lines of code in the body as you want

5. Methods have two parts This Body has two lines of code
It tells the computer to print to the screen the text that is inside the set of double quotes after skipping a blank line
public void message( ) {
System.out.println();
System.out.println(“java is not kawfy”); }

6. Create a Class To use the method we need to create a simple class
The class is like a tool bag
It can hold one or many tools (methods)
The class also has a Header and a Body

7. Create a Class The first part is called the Header
modifier structure name
public class MyMethods {
open & closing braces }

8. Create a Class The second part is called the Body
The body contains one or more methods
public class MyMethods {
public void message()
System.out.println();
System.out.println(“java is not kawfy”); }

9. Create an Application An Application is an executable program
It uses the methods of different classes to execute the program
Some methods are from the Java Class Library
Other methods are from the Classes that We wrote

10. Create an Application We will create an object (instance) of the class
We will call (use) a method of the class
The Application class also has a Header and a Body
The Application has one method named main

11. Create an Application Syntax: public class RunMyMethods {
public static void main(String [] args)
MyMethods mm = new MyMethods();
mm.message(); //class object calls method }

12. Compile and Run Compile … correct any syntax errors
Run … check for correct output
If necessary make any corrections
Then recompile and rerun.
