This is a trick question, there is no problem with the code and it will compile successfully. We can always catch an Exception or any unchecked exception even if it’s not in the throws clause of the method. Similarly, if a method (foo) declares an unchecked exception in the throws clau...
Answer:Debugging the code using system.out.println() will lead to manual scanning of the whole output every time the program is run to ensure the code is doing the expected operations. Moreover, in the long run, it takes lesser time to code Junit methods and test them on our files. Qu...
