Most of my BlueJ applications are updated for exception handling, so my programs will not crash if the user enters a wrong input value.

The continue statement goes back to the beginning of the loop, as long as the loop condition is still true. The break statement ends the loop immediately. These statements are often used in the while, do-while, and for loops. With the exception handled, the program will not crash. The statements in the try block are executed first, but if these statements fail, then the statements in the catch block gets executed instead, as long as it corresponds to the exception. An example of a try-catch blockįor example, say that the program prompts the user to enter a number, but what if the user types a non-numeric input instead? Then you as a programmer will need to handle the exception in some way, or else your program will crash! This is why the try-catch blocks are used to handle the exception. This is accomplished by the try-catch blocks. That means that the error message can be displayed on the output instead of letting the program crash.
