The try{}catch{} statement is a programming construct used in many programming languages to handle errors or exceptions that may occur during the execution of a program.
The try block contains the code that may cause an exception to occur, while the catch block contains the code that handles the exception.
When an exception occurs in the try block, the control is transferred to the catch block, where the exception is caught and some action can be taken to handle it.
The catch block can also be used to throw a new exception or rethrow the original exception, depending on the situation.
Overall, the try{}catch{} statement is an essential tool for writing robust and error-free code, as it allows developers to gracefully handle unexpected situations that may arise during program execution.
