No code can be between the. In this example, we marked a risky segment of code by encasing it within a try block. If any of the code in the try block can throw a checked exception, it has to appear in the throws clause of the method signature. If you try to compile the listofnumbers class, the compiler prints an error message about the exception thrown by the filewriter constructor. This tells the compiler that we're aware of a potential exception and that we're intending to handle it if it arises. We can handle it by rethrowing our exception: You associate exception handlers with a try block by providing one or more catch blocks directly after the try block.
