Conditional Increment — Apex Code
Increment counter only if below 5.
public class ConditionalIncrement {
public void run() {
Integer count = 3;
if(count < 5) count++;
System.debug('Counter: ' + count);
}
}
ConditionalIncrement ci = new ConditionalIncrement();
ci.run();Apex Language Guide
Apex is a strongly typed, object-oriented programming language developed by Salesforce for building scalable, secure, and automated applications on the Salesforce platform. It allows developers to execute business logic on the server side, integrate external systems, and customize CRM workflows using a syntax similar to Java.
Primary Use Cases
- ▸Salesforce triggers & automation
- ▸Custom REST & SOAP APIs
- ▸Batch & scheduled jobs
- ▸Complex CRM business logic
- ▸Integrations with external systems
- ▸Custom Salesforce Apps & packages
Notable Features
- ▸Java-like syntax
- ▸Strong typing & OOP design
- ▸Built-in Salesforce data access (SOQL/SOSL)
- ▸Asynchronous processing
- ▸Governor limits for resource control
Origin & Creator
Apex was introduced by Salesforce in 2006 as a proprietary cloud-based programming language enabling customization of the Force.com platform.
Industrial Note
Apex is widely used in enterprise CRM automation, financial workflow engines, healthcare records management, SaaS integrations, and large-scale automation pipelines inside Salesforce.
Quick Explain
- ▸Apex runs natively on Salesforce servers and is optimized for multitenant architecture.
- ▸It supports asynchronous processing, triggers, and declarative automation integration.
- ▸Used to build custom business logic, APIs, batch processes, and advanced CRM customizations.
Core Features
- ▸Classes & objects
- ▸Triggers for automation
- ▸SOQL/SOSL queries
- ▸Batch Apex, Queueable Apex, Scheduled Apex
- ▸Exception handling & testing framework
Learning Path
- ▸Learn Salesforce fundamentals
- ▸Master SOQL & DML
- ▸Write triggers
- ▸Learn async Apex
- ▸Integrate external systems
Practical Examples
- ▸Before/after insert trigger
- ▸REST API endpoint
- ▸Batch job processing thousands of records
- ▸Scheduled Apex cleanup
- ▸CRUD operations with SOQL
Comparisons
- ▸Similar syntax to Java
- ▸More restricted due to governor limits
- ▸Cloud-executed vs local execution
- ▸Deep CRM integration unlike general languages
- ▸Strict testing requirements
Strengths
- ▸Native integration with Salesforce objects
- ▸Secure, scalable execution
- ▸Excellent tooling and test framework
- ▸Great for enterprise automation
- ▸Powerful asynchronous capabilities
Limitations
- ▸Vendor lock-in to Salesforce ecosystem
- ▸Strict governor limits
- ▸Cannot interact with system file I/O
- ▸Restricted multithreading
- ▸Must follow Salesforce deployment rules
When NOT to Use
- ▸Front-end UI work (use LWC/Aura)
- ▸Heavy ML computation
- ▸File processing
- ▸Desktop apps
- ▸Systems that need OS-level access
Cheat Sheet
- ▸SELECT Id, Name FROM Account;
- ▸insert new Account(Name='Test');
- ▸System.debug('Log');
- ▸Test.startTest(); ... Test.stopTest();
- ▸@future callout=true
FAQ
- ▸Is Apex only for Salesforce?
- ▸Yes - it runs exclusively on the Salesforce platform.
- ▸Does Apex support multithreading?
- ▸No - but async patterns exist.
- ▸Do I need Java to learn Apex?
- ▸No - but Java experience helps.
