How to implement Runnable interface in Java?
But the Java Runnable interface does not have any support for threads. We must also create an instance of the Thread class, which is achieved through the constructor public Thread (Runnable target) of the Thread class; The following is an example:
public class MyThread implements Runnable { int count=1, number; public MyThread(int num) { numnumber = num; System.out.println("创建线程 " + number); } public void run() { while(true) { System.out.println("线程 " + number + ":计数 " + count); if(++count== 6) return; } } public static void main(String args[]) { for(int i = 0; i < 5; i++) new Thread(new MyThread(i+1)).start(); } }
Using the Java Runnable interface to implement multi-threading allows us to contain all code in one class, which is conducive to encapsulation. Let us study some issues in the use of multi-threading.

Java Cryptography Architecture (JCA) for Secure Coding
Aug 23, 2025 pm 01:20 PM
Understand JCA core components such as MessageDigest, Cipher, KeyGenerator, SecureRandom, Signature, KeyStore, etc., which implement algorithms through the provider mechanism; 2. Use strong algorithms and parameters such as SHA-256/SHA-512, AES (256-bit key, GCM mode), RSA (2048-bit or above) and SecureRandom; 3. Avoid hard-coded keys, use KeyStore to manage keys, and generate keys through securely derived passwords such as PBKDF2; 4. Disable ECB mode, adopt authentication encryption modes such as GCM, use unique random IVs for each encryption, and clear sensitive ones in time

Java Persistence with Spring Data JPA and Hibernate
Aug 22, 2025 am 07:52 AM
The core of SpringDataJPA and Hibernate working together is: 1. JPA is the specification and Hibernate is the implementation, SpringDataJPA encapsulation simplifies DAO development; 2. Entity classes map database structures through @Entity, @Id, @Column, etc.; 3. Repository interface inherits JpaRepository to automatically implement CRUD and named query methods; 4. Complex queries use @Query annotation to support JPQL or native SQL; 5. In SpringBoot, integration is completed by adding starter dependencies and configuring data sources and JPA attributes; 6. Transactions are made by @Transactiona
