Explain the difference between runnable and callable interface in java ?

How runnable interface is different from callable interface in java ?: Both runnable interface and callable interface in java are typically used to encapsulating the tasks that must be carried out by a different thread.  The article provides the major difference between the runnable interface and callable interface in java

Runnable Interface in java : 

• Runnable is a functional interface which is used to create a thread at runtime
• Runnable interface provides only abstract method run()
• When using runnable interface, multiple threads share the same objects
• When using runnable interface, memory consumption is less
• When using runnable interface , a class can extend another class
• Runnable interface is introduced in JDK 10

public class PlanforexamsLogger implements  Runnable{
    private Logger logger
      = LoggerFactory.getLogger(PlanforexamsLogger.class);

    @Override
    public void run() {
        logger.info("Messge from PlanforexamsLogger Class ...");
    }
}

Callable Interface in java : 

• Callable interface is part of the concurrent package in java 
• Callable interface is introduced in JDK 5.0 
• Callable interface provides the call() method to define a task
• Callable interface provides the result and thus throws an exception for the error occurred
