Advanced AI features enhance modern applications by making them more intelligent, interactive, and context-aware.
They go beyond basic text generation and enable systems to perform complex tasks like reasoning, memory handling, tool usage, and automation.
👉 These features are essential for building production-ready, scalable, and reliable AI systems.
👉 They help you move from a simple AI demo to a real-world, enterprise-level application.
Advanced AI features refer to powerful capabilities built on top of Large Language Models (LLMs) that improve performance, usability, and intelligence.
In simple words: these features make AI smarter, more useful, and closer to real-world problem solving.
Instead of just answering questions, AI can now remember, decide, act, and interact with systems.
Practical Example (AI Decision + Action Flow in Java)
public class AIAgent {
private final EmailService emailService;
private final MeetingService meetingService;
public AIAgent(EmailService emailService, MeetingService meetingService) {
this.emailService = emailService;
this.meetingService = meetingService;
}
public String processRequest(String userInput) {
// AI-like intent detection (simplified logic)
if (userInput.contains("send email")) {
emailService.sendEmail("[email protected]", "Hello from AI");
return "Email sent successfully";
}
if (userInput.contains("schedule meeting")) {
meetingService.schedule("Team Sync Meeting");
return "Meeting scheduled successfully";
}
return "No actionable intent found";
}
}
👉 This shows how AI systems can go beyond text generation and actually perform actions based on user intent.
👉 This is the base concept behind AI Agents and Tool Calling systems.
Streaming allows AI to send responses token by token in real-time.
Instead of waiting for the full response, users see output as it is generated.
👉 This improves user experience, especially in chat applications.
Practical Example (Streaming Response in Spring AI)
import org.springframework.ai.chat.client.ChatClient;
import reactor.core.publisher.Flux;
public class StreamingService {
private final ChatClient chatClient;
public StreamingService(ChatClient chatClient) {
this.chatClient = chatClient;
}
public Flux<String> streamResponse(String prompt) {
return chatClient.prompt()
.user(prompt)
.stream()
.content();
}
}
Controller Example (Real-Time Output API)
import org.springframework.web.bind.annotation.*;
import reactor.core.publisher.Flux;
@RestController
@RequestMapping("/ai")
public class StreamingController {
private final StreamingService streamingService;
public StreamingController(StreamingService streamingService) {
this.streamingService = streamingService;
}
@GetMapping("/stream")
public Flux<String> stream(@RequestParam String prompt) {
return streamingService.streamResponse(prompt);
}
}
Function calling allows AI to interact with backend logic or external APIs.
👉 This makes AI not just a responder, but a decision-maker and executor.
Practical Example (Java Tool Execution Logic)
public class BookingAgent {
private final BookingService bookingService;
public BookingAgent(BookingService bookingService) {
this.bookingService = bookingService;
}
public String handleRequest(String userRequest) {
if (userRequest.contains("book ticket")) {
bookingService.bookTicket("user123");
return "Ticket booked successfully";
}
return "No action matched";
}
}
👉 AI decides when to call backend functions based on user intent.
Multi-turn conversations allow AI to understand and maintain context across multiple user interactions.
Example:
User: “What is Docker?”
User: “How is it used in Kubernetes?”
Practical Example (Conversation Context Handling)
import java.util.ArrayList;
import java.util.List;
public class ConversationMemory {
private final List<String> history = new ArrayList<>();
public String chat(String userMessage) {
history.add(userMessage);
// Simulated context-aware response
if (history.size() > 1) {
return "Answer based on previous context + new query: " + userMessage;
}
return "First interaction: " + userMessage;
}
}
👉 AI stores previous messages and uses them to generate better responses.
Context memory stores past interactions to improve response relevance.
👉 Helps AI give more connected and personalized responses.
Practical Example (Session Memory Storage)
import java.util.HashMap;
import java.util.Map;
public class MemoryStore {
private final Map<String, String> userMemory = new HashMap<>();
public void savePreference(String userId, String data) {
userMemory.put(userId, data);
}
public String getPreference(String userId) {
return userMemory.getOrDefault(userId, "No memory found");
}
}
👉 This is how AI systems store and reuse user-specific context.
Prompt chaining breaks complex tasks into multiple smaller steps.
👉 This improves control, accuracy, and structure of AI output.
Practical Example (Prompt Chaining Flow in Java)
public class PromptChainingService {
public String generateEmail(String userInput) {
// Step 1: Generate summary
String summary = summarize(userInput);
// Step 2: Convert summary into email
String emailDraft = convertToEmail(summary);
// Step 3: Format email
return formatEmail(emailDraft);
}
private String summarize(String input) {
return "Short summary of: " + input;
}
private String convertToEmail(String summary) {
return "Email content based on: " + summary;
}
private String formatEmail(String email) {
return "Formatted Email:\\n" + email;
}
}
👉 Each step is broken into smaller tasks for better accuracy and control.
Caching stores previous AI responses to avoid repeated API calls.
Practical Example (Simple Cache Implementation)
import java.util.HashMap;
import java.util.Map;
public class AICacheService {
private final Map<String, String> cache = new HashMap<>();
public String getResponse(String query) {
if (cache.containsKey(query)) {
return cache.get(query); // return cached response
}
String response = callAI(query);
cache.put(query, response); // store response
return response;
}
private String callAI(String query) {
return "AI Response for: " + query;
}
}
👉 This avoids unnecessary AI API calls and saves cost.
Guardrails ensure AI responses are safe, controlled, and appropriate.
Practical Example (Basic Guardrail Filtering Logic)
public class GuardrailService {
public String validateResponse(String response) {
if (response.contains("hate") || response.contains("violence")) {
return "Response blocked due to safety policy.";
}
if (response.length() > 1000) {
return "Response too long, trimmed for safety.";
}
return response;
}
}
👉 This ensures AI output stays safe and controlled before showing to users.
AI usage can become expensive, so optimization is very important in production systems.
👉 The goal is to reduce unnecessary API calls and improve efficiency without affecting performance.
Best Practices (with Practical Logic)
👉 These techniques help build cost-efficient and scalable AI systems.
Practical Example (Token Optimization + Cache Check)
public class CostOptimizationService {
private final AICacheService cacheService;
public CostOptimizationService(AICacheService cacheService) {
this.cacheService = cacheService;
}
public String getOptimizedResponse(String query) {
// Step 1: Check cache first
String cached = cacheService.getResponse(query);
if (cached != null) {
return cached;
}
// Step 2: Optimize prompt (reduce token usage)
String optimizedPrompt = query.trim().toLowerCase();
// Step 3: Call AI only if needed
return callAI(optimizedPrompt);
}
private String callAI(String prompt) {
return "AI Response for: " + prompt;
}
}
👉 This reduces unnecessary API usage and saves cost.
Observability helps monitor, debug, and improve AI systems effectively.
👉 It provides visibility into how your AI system is performing in real time.
Key Components
👉 This is critical for production-grade AI systems.
Practical Example (Simple Logging + Monitoring)
import java.time.LocalDateTime;
public class ObservabilityService {
public String processRequest(String request) {
log("Request received: " + request);
String response = "Processed AI response for: " + request;
log("Response generated: " + response);
return response;
}
private void log(String message) {
System.out.println(LocalDateTime.now() + " | " + message);
}
}
👉 This helps track system behavior and debug issues easily.
AI agents can take actions, make decisions, and execute multi-step workflows automatically.
👉 They go beyond text generation and act like intelligent automation systems.
Practical Example (AI Agent Decision System in Java)
public class AIAgentService {
private final EmailService emailService;
private final MeetingService meetingService;
private final ReportService reportService;
public AIAgentService(EmailService emailService,
MeetingService meetingService,
ReportService reportService) {
this.emailService = emailService;
this.meetingService = meetingService;
this.reportService = reportService;
}
public String executeTask(String task) {
if (task.contains("email")) {
emailService.sendEmail("[email protected]", "AI Generated Email");
return "Email sent successfully";
}
if (task.contains("meeting")) {
meetingService.scheduleMeeting("Team Sync");
return "Meeting scheduled successfully";
}
if (task.contains("report")) {
reportService.generateReport();
return "Report generated successfully";
}
return "No valid action found";
}
}
This example shows how an AI system moves from understanding → action → response generation in a real-world workflow.
String query = "Schedule a meeting tomorrow";
// Step 1: Understand user intent
String intent = aiService.detectIntent(query);
// Step 2: Execute backend action based on intent
if ("schedule_meeting".equals(intent)) {
meetingService.schedule("Tomorrow");
}
// Step 3: Generate final response using LLM
String response = chatClient.prompt()
.user("Confirm meeting scheduled for tomorrow")
.call()
.content();
System.out.println(response);
