 # Graphical Application: _\*_ Catch the Button!
 
-Create a fun graphical application **„catch the button“**: a form consisting of one button. Upon moving the mouse cursor onto the button, it moves to a random position. This way it creates the impression that "**the button runs form the mouse and it is hard to catch**". When the button gets „caught“, a congratulations message is shown.

-In this case we choose to use the **conditional operator (`?:`)** (also called ternary operator), because the record is shorter. Its syntax is as follows: **`operand1 ? operand2 : operand3`**. First operand need to be **boolean type** (i.e. to return **`true/false`**). If **`operand1`** returns **`true`**, **`operand2`** will be executed, and if it returns **`false`** – **`operand3`** will be executed. In our case we check if the **money saved** by Lilly is enough for a washing machine. If it is more than or equal to the price of a washing machine, the check **`savedMoney >= priceOfWashingMachine`** will return **`true`** and will print  „**Yes! …**“, and if it is less – the result will be **`false`** and “**No! …**” will be printed. Of course, instead of conditional operand, we can use **`if`** checks.
