Controller Extensions Part 2

Here’s a sample code example for a Visualforce page with a standard controller and multiple controller extensions in Apex:

Visualforce Page (samplePage.page):

<apex:page controller="Account" extensions="SampleExtension1, SampleExtension2">
    <h1>Welcome to the Sample Page</h1>
    
    <apex:outputText value="Account Name: {!accountName}" />
    <apex:outputText value="Contact Name: {!contactName}" />
</apex:page>

Controller (SampleController.cls):

public class SampleController {
    public String accountName { get; set; }
    
    public SampleController() {
        // Initialization logic
        accountName = 'ABC Company';
    }
}

Controller Extension 1 (SampleExtension1.cls):

public class SampleExtension1 {
    private ApexPages.StandardController stdController;
    
    public SampleExtension1(ApexPages.StandardController controller) {
        stdController = controller;
    }
    
    public String getAccountName() {
        // Accessing the standard controller's record
        Account acc = (Account)stdController.getRecord();
        return acc.Name;
    }
}

Controller Extension 2 (SampleExtension2.cls):

public class SampleExtension2 {
    private ApexPages.StandardController stdController;
    
    public SampleExtension2(ApexPages.StandardController controller) {
        stdController = controller;
    }
    
    public String getContactName() {
        // Accessing the standard controller's record
        Contact con = (Contact)stdController.getRecord();
        return con.Name;
    }
}
