Final answer:
If an exception is thrown in a try{} block and there is no matching catch{} block, the program will terminate and an error message will be displayed.
Step-by-step explanation:
If an exception is thrown in a try{} block and there is no matching catch{} block, the program will terminate and an error message will be displayed. This is because the program does not know how to handle the exception if there is no appropriate catch{} block. However, it is possible to have a finally{} block after the try{} block that will always be executed.
However, it is possible to have a finally{} block after the try{} block. The code inside the finally{} block will always be executed, whether an exception is thrown or not. This allows for any necessary clean-up or finalization tasks to be performed.
Here is an example:
try {
// Code that may throw an exception
} finally {
// Code that will always be executed
}
