How does a try-catch statement work? Why are they important? Describe a situation in which one might be helpful.
What will be an ideal response?
A try-catch statement includes two clauses: try and catch. The statements within the try clause are executed until one of them throws an exception. If this happens, an exception object is created and sent immediately to the catch clause, at which point the catch clause executes. If no statement throws an exception, the catch clause is skipped.
Try-catch statements are helpful because the provide a mechanism for a program to handle invalid input without stopping the program. They detect and respond to exceptions without halting the program.
A try-catch statement would be helpful in a situation where a user inputs an invalid number, or one in an invalid format, such as ‘12r8' instead of ‘1258.'
