First, create a class that properly implements the ‘Runnable’ interface. Remember, this interface has only one function that the class must implement: ‘run()’. The ‘run()’ method implementation must includ
// Declares String reference variable str1 and str2 String str1; String str2; // Assigns the reference of a String object "Hello" to str1 str1 = new String( "Hello World !!" ); // Assigns the reference stored in str1 to str2 str2 = str1; System.out.println( str1 ); //Hel...

We can use thestart()method to execute threads created usingRunnableinterface. classSubTaskWithRunnableimplementsRunnable{publicvoidrun(){System.out.println("SubTaskWithRunnable started...");}}ThreadsubTaskWithRunnable=newThread(newSubTaskWithRunnable());subTaskWithRunnable.start(); Using the lambda ...
solution 02:alternatively, we may create two parallel threads by deriving our class from the "Thread" class. in this case, we also have to provide a "run" method, becauseThreaduses theRunnableinterface. :load csj01x3.java this produces the same output as solution 01, but it has one trad...

In limited cases, such as when overriding a method that doesn't throw any checked exceptions or implementing the Runnable interface, it is sensible to account for the possibility of theInterruptedExceptionexception being thrown, but let the program move forward without crashing. In this type of sce...
We canpropagate it up in the stack to the caller method by usingthrowskeyword. In this case, the caller method needs to handle this exception. There are some scenarios where throwing an exception is not possible like in case ofRunnableinterfacerun()method, it won’t allow throwing an excepti...
