Method 3: Select a Runtime to add to the classpath
Java Build Path > Libraries > Add Library > Server Runtime > Next (As shown in Image)
then select a Runtime(Apache Tomcat Server) > Finish > OK (As shown in Image)

Save/Paste this file on following location :
C:\Documents and Settings\<username>\Application Data\uTorrent (For Windows XP, 2003 and 2000).

In Oracle using ROWNUM :
For each row returned by a query, the ROWNUM pseudocolumn returns a number indicating the order in which Oracle selects the row from a table or set of joined rows. The first row selected has a ROWNUM of 1, the second has 2, and so on.
You can use ROWNUM to limit the number of rows returned by a query, as in this example:
SELECT Cols |* FROM table_name WHERE ROWNUM < Number;
Example to find the 3rd highest salary using Oracle Database:
Employee Table :
Sql Command in action in Oracle Database
In SQL using SELECT TOP clause :
The SELECT TOP clause is used to specify the number of records to return, as in this example:
SELECT TOP number|percent column_name(s) FROM table_name;
Example to find the 3rd highest salary using MySql Database:
Query 1: SELECT MIN(SALARY) AS Salary FROM Employee WHERE SALARY IN (SELECT DISTINCT TOP 3 SALARY FROM Employee ORDER BY SALARY DESC);
Query 2 : SELECT Top 1 Salary AS Salary FROM Employee WHERE SALARY IN (SELECT DISTINCT TOP 3 SALARY FROM Employee ORDER BY SALARY DESC) ORDER BY SALARY;
Also Read : SQL : Find 2nd or 3rd highest salary from employee table without ROWNUM or TOP

Solution : Here I am using Windows 8.1 and Java 8.
1. Check out Maven in your Apache Tomcat Directory. If Maven folder is not there then download it first from this site : https://maven.apache.org/download.cgi

Unzip it and paste "apache-maven-3.3.3" inside "apache-tomcat-7.0.54" as I'm using Apache 7.
2. Create a user variables like this [ M2 = %M2_HOME% ]
3. Create a user variables like this [M2_HOME = F:\apache-tomcat-7.0.54\apache-maven-3.3.3\bin]
(as my apache tomcat is in F:\ dive your may be in C:\ drive)
4. Edit the Path or PATH to [What ever is already in here +];%M2%
5. Dependency in pom.xml
6. Now open Command Prompt go-to "F:\apache-tomcat-7.0.54\apache-maven-3.3.3\bin"

USB Debugging grants you a level of access to your device. This level of
access is important when you need system-level clearance, such as when
coding a new app.USB Debugging Mode is a mode that can be enabled in Android after
connecting the device directly to a computer with a USB cable. The
primary function of this mode is to facilitate a connection between an
Android device and a computer with Android SDK (software development
kit).
1. Android 2.0-2.3.x
Settings > Applications > Development > USB Debugging
2. Android 3.0- 4.1.x
Settings > Developer Options > USB Debugging
3. Android 4.2.x and higher.
- Go to "Settings".
- Scroll down to the bottom and tap "About phone" or "About tablet",
- Scroll down to the bottom of the "About phone" and locate the "Build Number" field.
- Tap the Build number field few times to enable Developer Options.
Tap a few times and you'll see a countdown that reads "You are now 3
steps away from being a developer."
- When you are done, you'll see the message "You are now a developer!".
- Tap the Back button and you'll see the Developer options menu under System on your Settings screen.
- Go to Settings>Developer Options>USB Debugging. Tap the USB Debugging checkbox.
4. Android 5.0 Lollipop
- Settings > About Phone > Build number > Tap it few times to become developer
- Settings > Developer Options > USB Debugging
NOTE: To disable USB Debugging and other developer options when you don't need them, slide the switch at the top of the screen from On to Off.
