In Salesforce, Apex and Visualforce Controllers are used to control the flow of data and user interactions in web applications built on the Salesforce platform. The Apex language is used for backend programming, while Visualforce is used for frontend design.
An apex:message component is used to display a message for a specific component on a Visualforce page. This component is often used to display warning or error messages when user input is incorrect or when an error occurs during data processing.
If an apex:message or apex:messages component is not included in a Visualforce page, most warning and error messages are only shown in the debug log. This means that users will not be alerted to any errors or warnings that occur during data processing, and it will be up to the developer to monitor the debug log for any issues.
The apex:flash component is used to display a temporary message to the user after a page is submitted or refreshed. This component is useful for displaying confirmation messages or status updates.
The apex:detail component is used to display detailed information about a specific record on a Visualforce page. This component is often used in conjunction with the apex:pageBlock component to display a record's fields and related lists.
The apex:listViews component is used to display a list of records that meet certain criteria on a Visualforce page. This component is often used to create custom views of data for specific user roles or departments.
