The "try/catch" structure is a way for programmers to handle errors in their code. When you put code inside a try block, you're telling the program to attempt running that code. If everything goes smoothly, the program continues as normal. However, if an error occurs, the program jumps to the catch block, where you can define how to respond to the error, like showing a message to the user or logging the issue. This approach helps keep programs running smoothly, even when unexpected problems arise. By using "try/catch," developers can create more robust applications that handle issues gracefully, improving the overall user experience.
