1.What is the difference between map and set in Salesforce collections.
Map:
To declare a set, use the Set keyword followed by the primitive data type name within <> characters. For example:
Map:
A map is a collection of key-value pairs where each unique key maps to a single value. Keys can be any primitive data type, while values can be a primitive, sObject, collection type or an Apex object. For example, the following table represents a map of countries and currencies:
| Country (Key) | 'United States' | 'Japan' | 'France' | 'England' | 'India' |
| Currency (Value) | 'Dollar' | 'Yen' | 'Euro' | 'Pound' | 'Rupee' |
Similar to lists, map values can contain any collection, and can be nested within one another. For example, you can have a map of Integers to maps, which, in turn, map Strings to lists. A map can only contain up to five levels of nested collections inside it.
Set:
A set is an unordered collection of primitives or sObjects that do not contain any duplicate elements. For example, the following table represents a set of String, that uses city names:
| 'San Francisco' | 'New York' | 'Paris' | 'Tokyo' |
2. Why Use Triggers?
Triggers are used to perform immediate actions based on previous action e.g. field update. An apex language is used to write triggers
3. What are different types of Triggers?
There are two types of triggers
a) Before trigger- is used before database operation
b) After trigger-is used to access field values
that are set by the database (such as a record's Id or lastUpdated field), and to affect changes in other records,
such as logging into an audit table or firing asynchronous events
with a queue.
4. Why Use Visual Force?
Visual force is a Sales force UI markup language using visual force we can construct WebPages. In Sales force MVC architecture Visual force represents View.
5. How do you handle errors?
Error handing is done directly displaying in Visual force page using Apex Pages methods to end users or displaying in debug logs.

62.What is the diff between Rendering and Re-Rendering tags?
| renderAs | String | The
name of any supported content converter. Currently PDF is the only
supported content converter. Setting this attribute to "pdf" renders the
page as a PDF.
Rendering a Visualforce page as a PDF is intended for
pages that are designed and optimized for print. Standard components
that aren't easily formatted for print or contain form elements like
inputs, buttons, any component that requires JavaScript to be formatted,
shouldn't be used. This includes but is not limited to, any component
that requires a form element. Verify the format of your rendered page
before deploying it.
If the PDF fails to display all the
characters, adjust the fonts in your CSS to use a font that supports
your needs. For example, add the following style definition to your
page's styles:
body { font-family: 'Arial Unicode MS'; }
Note that the pageBlock and sectionHeader components don't support double-byte fonts when rendered as a PDF.
