Playing with Annonymous inner class

Annonymous inner class

Thread T= new Thread()
{};
//annonumous inner class extends Thread class, in short it's  extedns parent Thread

Runnable R= new Runnable()
{
};
is it possible , yes
it's not runnable object it's an object of annonumous class which implement Runnable
else you can't crate an object of Interface

Example

public class AnnnerClass {

public static void main(String[] args) {

A a=new A()
{

public void m1()
{

System.out.println("spicy");
}
};

a.m1();

}
}

public class A {

public void m1()

{

System.out.println("swetty");

}

}

here annonymous A extends A,  and call child class object. 

What is Splunk and How Does it Work?

The general idea is that Splunk can take any data, any log, from anywhere in your infrastructure and add it to a searchable, intelligent index through which you can extract all sorts of meaningful data about what's happening. By default, the system will watch all the logged events and return slices of interesting data. For instance, from the dashboard you can see that a specific server name or event type is occurring at a higher than normal frequency. From there, you can drill down and chase the cause of the error from the hypervisor to the storage, networking, and even the VM.

there are some video lecture also available in it. you can  check online

If there's gold in log files, Splunk, Inc's Splunk Enterprise will help you to find it. Splunk bridges the gap between simple log management and security information and event management (SIEM) products from vendors such as ArcSight, RSA, Q1 Labs, and Symantec.
