Here’s an example of a multi-threaded Java program that runs two threads in parallel:

public class MultiThreadExample extends Thread {
public void run() {
for (int i = 1; i <= 5; i++) {
System.out.println(Thread.currentThread().getName() + " - Count: " + i);
try {
Thread.sleep(500); // Pauses execution for 500 milliseconds
} catch (InterruptedException e) {
System.out.println(e);
}
}
}
public static void main(String[] args) {
    MultiThreadExample thread1 = new MultiThreadExample();
    MultiThreadExample thread2 = new MultiThreadExample();

    thread1.start(); // Starts thread1
    thread2.start(); // Starts thread2
}
}
  • In this code:
    • MultiThreadExample extends the Thread class and overrides the run method, which is the code each thread will execute.
    • Thread.sleep(500) pauses the thread for 500 milliseconds, allowing other threads to execute.
    • start() begins execution of each thread, allowing both thread1 and thread2 to run simultaneously.
    • Performance Optimization: Java has built-in garbage collection to manage memory, and its tools like the Java Virtual Machine (JVM) offer options for memory management and performance tuning, making it ideal for large-scale applications.

@RestController
public class HelloController {
   @GetMapping("/hello")
   public String sayHello() {
    return "Hello, Spring!";
   }
}

In this example:

  • The @RestController annotation defines a controller for handling web requests.@GetMapping("/hello") specifies that this method should respond to GET requests to the /hello endpoint.The sayHello() method returns a simple greeting.

  • Hibernate: This ORM (Object-Relational Mapping) framework simplifies working with databases by mapping Java objects to database tables. Here’s an example of a Hibernate entity class:

import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class User {

   @Id
   private Long id;
   private String name;
   private String email;

   // Getters and Setters
   public Long getId() {
     return id;
   }

   public void setId(Long id) {
     this.id = id;
   }

   public String getName() {
     return name;
   }

   public void setName(String name) {
     this.name = name;
   }

   public String getEmail() {
     return email;
   }

   public void setEmail(String email) {
     this.email = email;
   }
}

In this example:

  • The @Entity annotation marks this class as a database entity, making it ready to be mapped to a table.
  • @Id identifies the id field as the primary key in the database.
  • Hibernate automatically handles SQL operations for this entity, reducing the need to write boilerplate SQL code.
