10C. Write a Java program that creates a user interface to perform integer divisions.
The user enters two numbers in the text fields, Num1 and Num2. The division of Num1
and Num2 is displayed in the Result field when the Divide button is clicked. If Num1 or
Num2 were not an integer, the program would throw a Number Format Exception. If
Num2 were Zero, the program would throw an Arithmetic Exception Display the
exception in a message dialog box.

STEP 4:
The default port number for Tomcat to process HTTP requests is 8080. You can either
change the port number here or change it later after the installation in server.xml which
is located in /conf/server.xml. We recommend to have the default value.
You can provide the username and password for Administrator login but here, we leave
it as blank.
Now, click on the „Next„ button.

STEP 5:
The installer uses the registry to determine the base path of a Java 5 or later JRE,
including the JRE installed as part of the full JDK.
When running on a 64-bit operating system, the installer will first look for a 64-bit JRE
and only look for a 32-bit JRE if a 64-bit JRE is not found.
It is not mandatory to use the default JRE detected by the installer. Any installed Java 5
or later JRE (32-bit or 64-bit) may be used by clicking on the browse button and click
„Next„.

STEP 6:
In Windows, by default the location will be provided as „C:\Program Files\Apache
Software Foundation\Tomcat 6.0′. But for simplicity, we recommend you to use
„C:\Tomcat6„ as shown below and click „Install„.
