When is exception handling necessary for stream handling?
Exception handling is necessary for string handling as there might be some unexpected situation during string handling which may lead to program crash or abrupt termination
Is exception handling implicit or explicit?
In Java, Exception Handling is Explicit. The Programmer has to write code that will ensure that the exceptions are caught and appropriately handled
Why do you need exception handling codes in a program?

How do you use try block in cpp?
A try statement is used in conjunction with one or more catch blocks to provide exception handling. If an exception is thrown by a try block, the corresponding catch block will handle the exception. If no catch block is provided for a particular exception, then a runtime error occurs instead. Try-catch statements are used to provide graceful resolutions to potential runtime errors.

Exception handling should be used in Java in all cases where you as a programmer suspect that your code might throw some exceptions or create errors that might look ugly when a user is using the application. In such cases you use exception handling to catch and handle the exception and exit gracefully. You use the try - catch block in Java for exception handling.
