The try-catch block is a programming construct that allows you to handle errors gracefully. It consists of two parts: the try block, which contains the code that might throw an error, and the catch block, which contains the code that will be executed if an error is thrown. For example, consider the following code:  try {
// Code that might throw an error
} catch (Exception e) {
// Code to handle the error
} If an error is thrown in the try block, execution will immediately jump to the catch block. The exception object (e) will contain information about the nature of the error, and you can use this information to take appropriate action. In many cases, simply logging the error message can be sufficient. Once the catch block has finished executing, execution will resume at the point where the try-catch block was called. Try-catch blocks can be nested, allowing you to create multiple levels of protection against errors.
