#Modified Access Control In Java

Access modifiers are keywords which define the accessibility of a class and its members. Access modifiers are used in Java to control the visibility (accessibility) of classes, interfaces, variables, methods, constructors, data members, and setter methods. . . . . . . . . #coding #software #softwaredeveloper #job #faang #google #amazon #development #developer #career #singleinheritance #programming #leetcode #codingquestions #googleinterview #microsoftinterview #softwareengineer #amazonjobs #softwaredevelopment #problemsolving #javaconcepts #interview #dynamicprogramming #oops #java #accessmodifier #dsa #datastructures #algorithm #itsruntym

Interviewer: How would you protect your APIs from unauthorized access and overuse? Unlock 200+ practical problem-solutions just like this one in the Ebook. Link in bio ⸻ 1️⃣ Authentication & Authorization – Verify who’s calling and what they can do. Example: Like checking ID before entry. How: Use OAuth 2.0, JWT tokens for secure access. ⸻ 2️⃣ Role-Based Access Control (RBAC) – Give users permissions based on their roles. Example: Like an admin having extra keys. How: Use Keycloak or Auth0 RBAC to manage user roles. ⸻ 3️⃣ Rate Limiting & Throttling – Limit how many requests a user can send per minute. Example: Like letting only 100 cars per minute through a toll gate. How: Configure Nginx, Kong, or API Gateway. ⸻ 4️⃣ API Gateway & WAF – Filter and block suspicious or harmful traffic. Example: Like guards checking bags at entry. How: Use AWS WAF, Kong, or Cloudflare to block attacks. ⸻ 5️⃣ Encryption (HTTPS / TLS) – Protect data in transit so attackers can’t modify it. Example: Always serve APIs over HTTPS, not on HTTP. How: Enable TLS via Nginx, Let’s Encrypt, or Cloudflare SSL. ⸻ 6️⃣ Monitoring & Alerts – Track traffic and detect suspicious activity. Example: Like CCTV spotting intruders early. How: Use Datadog, Prometheus, or CloudWatch for alerts. ⸻ 💡 Interview Tip: Explain security in 3 layers — Authentication (who), Authorization (what), and Rate Limiting (how often). Then mention API Gateway + Monitoring for bonus points. End with Encryption and Key Rotation to show depth. 🔥 #APISecurity #BackendEngineering #OAuth2 #JWT #RateLimiting #SecureAPI #BackendDeveloper #Microservices #APIGateway #CloudComputing #SoftwareEngineering #CyberSecurity #TechEducation #ScalableSystems { APISecurity, SpringBoot, JavaDeveloper, TechArchitect, Scalability, JavaTips, SystemDesign, MicroservicesArchitecture, SpringSecurity, JavaMicroservices, SecureAPI, BackendEngineering, RateLimiting, OAuth2, EngineeringSimplified, JWTToken, APIProtection, JavaCoding, TechReels, DevContent, TechExplained, , CloudSecurity, ScalableSystems, , Developer Tips, CyberSecurityBasics}

Implement a thread-safe Singleton class in Java using the double-checked locking Sol: To create a thread-safe Singleton class using double-checked locking in Java, we have to follow below steps: - Declare a private static volatile instance variable. - Define a private constructor to prevent instantiation from outside the class. - Implement a public static method that returns the Singleton instance, using double-checked locking. Implementation: public class Singleton { // Volatile keyword ensures that changes to the uniqueInstance variable are visible to all threads. private static volatile Singleton uniqueInstance; private Singleton() {} public static Singleton getInstance() { if (uniqueInstance == null) { // First check (without locking) synchronized (Singleton.class) { if (uniqueInstance == null) { // Second check (with locking) uniqueInstance = new Singleton(); } } } return uniqueInstance; } } #Java #Programming #Coding #SoftwareDevelopment #JavaProgramming #SingletonPattern #DesignPatterns #TechTips #CodeSnippet #ProgrammersLife #TechEducation #LearnToCode #Developer #CodeNewbie #JavaDevelopers #TechCommunity #ThreadSafety #Concurrency #CodingLife #TechInspiration
