Jeykll supports the use of [Markdown](http://daringfireball.net/projects/markdown/syntax) with inline HTML tags which makes it easier to quickly write posts with Jekyll, without having to worry too much about text formatting. A sample of the formatting follows.

__Modifiers__ fall into _two_ categories:
7+
8+
* __Access modifiers__: `public, protected, private and default (package-level access)`.
9+
* __Non-access modifiers__: `transient, synchronized, native, strictfp, final, abstract and static`.
10+
11+
### Access Modifiers
12+
13+
Two __types of access__ are there:
14+
15+
* Whether method code in one class can access a member of another class
16+
* Whether a subclass can inherit a member of its superclass
17+
18+
A **default member** may be accessed only if the class accessing the member belongs to the same package,
19+
whereas a **protected member** can be accessed by a subclass in the same package _(through dot operator and inheritance)_ and even if it is
20+
is in a different package _(through inheritance only)_.
21+
22+
You cannot access a protected member using the dot (.) operator in the
23+
subclass **if the subclass is in a different package** from the parent class.
24+
25+
The following code snippet makes it clear:
26+
27+
{% highlight java %}
28+
package certification;
29+
public class Parent {
30+
protected int x = 9; // protected access
31+
}
32+
33+
package other;
34+
import certification.Parent;
35+
class Child extends Parent {
36+
public void testIt() {
37+
System.out.println("x is " + x); // No problem; Child
38+
// inherits x
39+
Parent p = new Parent(); // Can we access x using the
40+
// p reference?
41+
System.out.println("X in parent is " + p.x); // Compiler
42+
// error
43+
}
44+
}
45+
{% endhighlight %}
46+
47+
#### The below table gives the picture of all access modifiers:
48+
49+
Visibility | Public | Protected | Default | Private
50+
------------------------------------------------- | -------- | -------------------------------- | --------- | ---------
51+
From the same class | Yes | Yes | Yes | Yes
52+
From any class in the same package | Yes | Yes | Yes | No
53+
From a subclass in the same package | Yes | Yes | Yes | No
54+
From a subclass outside the same package | Yes | Yes, through inheritance | No | No
55+
From any non-subclass class outside the package | Yes | No | No | No
56+
57+
### Non-Access Modifiers
58+
59+
**Final** is the only modifier which can be applied to local variables. It can also be used in method arguments like:
60+
{% highlight java %}
61+
// final in method arguments, can't be altered inside the method
62+
public Record getRecord(int fileNumber, final int recordNumber) {}
63+
{% endhighlight %}
64+
65+
A method can never, ever, ever be marked as both **abstract and final, or both abstract and private**.
66+
67+
#### Comparison of modifiers on variables vs. methods:
68+
69+
Local Variables | Non-local Variables | Methods
70+
------------------ | ----------------------- | --------
71+
final | final | final
72+
| public | public
73+
| protected | protected
74+
| private | private
75+
| static | static
76+
| transient | abstract
77+
| volatile | synchronized
78+
| | strictfp
79+
| | native
80+
