    Which of the following is true regarding try blocks in Java language?

    • Try blocks must be placed below a catch block

    • Try blocks must have at least one corresponding catch block

    • They always use recursion

    • Try blocks are only used for Exceptions related to file input and output

    Correct Answer
    A. Try blocks must have at least one corresponding catch block
    Explanation
    Try blocks must have at least one corresponding catch block in Java language because try blocks are used to enclose the code that may throw an exception, and the catch block is used to handle the exception that is thrown. Without a catch block, the code would not be able to handle the exception and would result in a compilation error. Therefore, it is necessary to have a catch block for every try block to handle the potential exceptions.

    I will cause a complier error if you did not declare/handle me in your program. I am :

    • Checked Exception

    • Unchecked Exception

    • All Exceptions

    • Option 4

    Correct Answer
    A. Checked Exception
    Explanation
    Checked Exception - the name itself suggests it is checked by the Java compiler!! You can not move ahead with execution of your program if you have these exceptions in your coding.

    An instance of _________ describes system errors. If this type of error occurs, there is little you can do beyond notifying the user and trying to terminate the program gracefully.

    • RunTimeException

    • Exception

    • Error

    • NumberFormatException

    Correct Answer
    A. Error
    Explanation
    An instance of "Error" describes system errors. If this type of error occurs, there is little you can do beyond notifying the user and trying to terminate the program gracefully. Errors are typically caused by serious problems that cannot be easily recovered from, such as out of memory errors or stack overflow errors. They are not meant to be caught and handled like exceptions, but rather indicate a severe problem that may require intervention from the developer or system administrator.

    Two classes of exceptions you should ideally deal in your program are:

    • Checked Exceptions

    • Runtime Exceptions

    • Error class

    • All Exceptions

    Correct Answer(s)
    A. Checked Exceptions
    A. Runtime Exceptions
    Explanation
    In Java, there are two main types of exceptions that should ideally be dealt with in a program: Checked Exceptions and Runtime Exceptions. Checked Exceptions are the exceptions that are checked at compile-time and are required to be handled or declared in the method signature. They are typically used to handle anticipated errors or exceptional conditions that can occur during the execution of a program. Runtime Exceptions, on the other hand, are not checked at compile-time and do not require explicit handling. They are usually caused by programming errors or unexpected conditions that may occur during the runtime of a program. Therefore, it is important to handle both types of exceptions to ensure proper error handling and program stability.
