The string data type should be used.

The enum data type should be used.

The integer data type should be used.

The container composite data type should be used.

You need a conditional statement that checks if a variable equals “In progress,” “Completed,” or “Canceled.” Different code needs to run, depending on what the variable equals. A default block of code needs to run if the variable does not equal any of the values. What conditional statement is most appropriate?

Error handling

A ternary operation

If statement

Switch statement

An error is sometimes thrown in a certain try…catch block. You know that the issue can be fixed within the code during the error handling code block. What statement could you use when the error is found to run the code again?

The throw statement should be used in the catch statement to rerun the try block.

The finally statement should be used in the catch statement to rerun the try block.

The retry statement could be used in the catch statement to rerun the try block.

A business system function should be used in the catch statement to rerun the try block.
